Why Tesla's AI trainers don't trust its self-driving tech - or its safety stats
Tesla says its Full Self-Driving software is up to 10 times safer than human drivers. But the figures the company uses to support its claims don't withstand scrutiny - and staffers who trained the technology say it isn't close to safely delivering autonomous vehicles at scale. In a Utah office, hundreds of Tesla workers scrutinize video collected by vehicles using the automaker's Full Self-Driving (FSD) feature. Some clips show the cars hitting cats, dogs or deer, along with more-routine accidents. Sometimes, they don't brake before impact. Often, they speed. Occasionally, the workers see near-misses of children playing in the street. Known as "data labelers," these staffers train Tesla's AI-powered driver-assistance software. They annotate incidents of good and bad driving and escalate problems to engineers working to improve the system. Tesla CEO Elon Musk says FSD will soon make all Teslas fully autonomous. But interviews with nine former labelers and a former Tesla self-driving engineer show that the technology continued to struggle in recent months to execute basic maneuvers - such as avoiding emergency vehicles or stopping for school buses loading or unloading students. Despite such dangerous shortcomings, Musk and other executives have increasingly touted FSD's safety as they pushed Tesla to stage public displays of the fully autonomous capability the CEO has promised investors every year for a decade. The displays include a robotaxi pilot in Austin, Texas - launched last June with some human safety monitors in the cars and others working remotely. Inside Tesla, as these events approached, staffers worked long hours mapping routes and training the software on specific hazards to make the company's self-driving technology appear more capable than it really is, four of the former Tesla employees told Reuters. The staffers said these labor-intensive safeguards are impossible to deploy on a broad scale. Those efforts, which haven't been previously reported, undermine Musk's long-stated claim that Tesla's self-driving technology will soon work anywhere globally and doesn't require the same laborious local mapping of roads and hazards employed by rivals. Musk has said Tesla takes a simpler approach, relying solely on cameras and AI, that will allow it to scale up its robotaxi service at "hyperexponential" speed and offer current Tesla owners full autonomy through software updates. Musk and other Tesla leaders have bolstered the impression of robo-competence by citing company safety statistics that they say prove FSD is already up to 10 times safer than human drivers. A Reuters examination of Tesla's statistical methodology and interviews with company insiders show Tesla isn't close to safely delivering self-driving vehicles at scale - a central promise underpinning the automaker's $1.6 trillion stock-market value. Elon Musk and other Tesla leaders have touted FSD's safety, citing company statistics that they say prove the technology is already up to 10 times safer than human drivers. The examination included a Reuters analysis of how Tesla compares its own crash data to federal crash data; a review of the comparatively rigorous methodology employed by robotaxi competitor Waymo; and interviews with 11 traffic-safety researchers who reviewed Tesla's methodology for Reuters. The review found several invalid data comparisons underlying the statistics in Tesla's FSD safety report, which 10 researchers said amounted to misleading marketing rather than a serious investigation into a critical safety issue. Tesla, for instance, exaggerates the technology's safety by comparing a rate of crashes in FSD-piloted Teslas that triggered airbag deployments to a federal crash rate for all vehicles that includes far less-severe accidents. The company also compares its cars to the average U.S. vehicle - which is much older than the average Tesla. That distorts the results because all automakers have recently launched new safety features that reduce crashes, the researchers said. "Any new car is dramatically safer than a 12-year-old car," said Phil Koopman, a Carnegie Mellon University engineering professor and autonomous-vehicle safety expert. "It's like saying: 'My jet airplane is faster than your World War II bomber.' Yeah, so, what's your point?" Tesla didn't respond to detailed questions from Reuters for this report. Tesla's CFO, Vaibhav Taneja, first made the 10-times-safer claim last July, after Tesla's Austin robotaxi launch. Tesla Board Chair Robyn Denholm repeated it at a November meeting where shareholders approved a pay package granting Musk up to $1 trillion in Tesla stock. Musk, at the same meeting, displayed a chart with the slightly more modest claim of "85% less crashes," based on recently revised Tesla methodology. "We almost feel comfortable allowing people to text and drive, which is kind of the killer app," Musk told shareholders. "In the next month or two - we're going to look closely at the safety statistics - but we will allow you to text and drive, essentially." Six months later, Tesla hasn't greenlit texting and driving with FSD. The fine print on its FSD website continues to warn: "Currently enabled features require active driver supervision and do not make the vehicle autonomous." Tesla has often cited such disclaimers when sued over serious accidents. FSD is widely regarded as capable of navigating many driving situations, sometimes for long periods. But full autonomy has proven elusive for Tesla and other companies, as it demands flawless execution by the technology - including in the most complex driving scenarios. Seven of the former data labelers told Reuters they wouldn't trust FSD to drive them. "We have all seen it fail," one said. Another said he wouldn't ride in a Tesla robotaxi "if you fucking paid me." One veteran self-driving engineer, who reviewed Tesla crash data for years, called its safety claims "bullshit." "Definitely," the engineer said, "don't trust Elon on this." 'TRAUMA TEAM' REVIEWS NEAR MISSES Tesla's data labelers get a close-up view of FSD's capabilities as they review footage from vehicles equipped with eight exterior cameras. The former employees reported regularly seeing FSD fail at basic tasks, including pulling over for emergency vehicles and giving motorcyclists enough space. Sometimes, they saw FSD-piloted vehicles fail to brake on freeway off-ramps, including a case where a Tesla hit a concrete wall. (The footage, they said, didn't show whether anyone was hurt.) Two employees said clips showed FSD failing to avoid construction zones. In one such incident, a Tesla drove into the zone, nearly striking workers, one of the people said. Reuters did not review the videos; this account is drawn from the former staffers' descriptions of footage they viewed. Inside Tesla, managers carefully controlled access to the videos. Because employees only see clips they're assigned, they may or may not see FSD's worst failures. One data-labeling team focused on near-misses of pedestrians, three employees said. Known informally as the "trauma team," one source said, these employees worked in Palo Alto, California, with special permissions to view the footage. Engineers closely guarded the trauma-team clips, but some footage would occasionally "slip through" to other teams, the person said. The person and another employee said they saw clips showing drivers manually taking over at the last second when FSD failed to recognize pedestrians in crosswalks. Two other former employees recalled seeing videos last year of FSD-piloted Teslas nearly hitting children. Tesla has for years faced federal investigations and lawsuits involving crashes, including fatalities, that drivers or regulators blamed on failures of FSD or its older Autopilot advanced driver-assistance system. The U.S. National Highway Traffic Safety Administration (NHTSA) opened an investigation into Autopilot in 2021 after a series of collisions involving Teslas striking emergency vehicles. The investigation led to a 2023 recall in which Tesla installed software upgrades to better detect when drivers stop paying attention and alert them. NHTSA has four active investigations into FSD and Autopilot, including one involving dozens of cases where vehicles using FSD failed to stop for red lights or turned into oncoming traffic. Another one probes whether Tesla's 2023 upgrades to Autopilot were sufficient to address the safety problems. The agency is also investigating at least nine FSD-involved incidents, including a fatal crash, where the system failed because of reduced visibility in conditions such as fog or sun glare. Tesla last year was hit with a $243 million verdict after an Autopiloted Tesla crashed in Florida, killing a 22-year-old woman and severely injuring her boyfriend. Tesla has appealed. The company has settled several similar cases involving serious crashes without disclosing terms. When asked by Reuters, NHTSA didn't address the findings in this story about FSD safety and Tesla's methodology. The agency referred questions about Tesla's safety claims to the U.S. Federal Trade Commission (FTC). The FTC declined to comment on Tesla's safety statistics. Some consumer advocacy groups and U.S. senators have called on the FTC to investigate Tesla's marketing of Autopilot and FSD. The FTC has brought no enforcement actions against Tesla. A Full-Self Driving demonstration in Amsterdam in April. The automaker continues to warn: "Currently enabled features require active driver supervision and do not make the vehicle autonomous." INFLATED STATS ON TESLA FSD SAFETY As Tesla employees watched videos of FSD's missteps, the company's board and CEO ramped up their claims about the technology's safety and readiness for full autonomy. For much of last year, leaders at Tesla promoted the 10-times-safer claim. "A car on FSD being 10x safer" will drive sales, Tesla CFO Taneja said in a July earnings call. "Even at $99 a month, it's like you're getting a personal chauffeur for almost $3.33 a day." A key problem with Tesla's methodology stems from one comparison error that inflated Tesla's claimed level of safety by a factor of three. The automaker counted Tesla crashes with airbag deployments and compared them with federal data on all crashes in which a tow-truck removed a vehicle - a far less restrictive criterion. Crashes requiring tow trucks often aren't severe enough to trigger airbags. Tesla took this apples-and-oranges approach even though apples were readily available for comparison: The federal data it used included crashes where airbags deployed. This flawed methodology produced the finding that Teslas using FSD or Autopilot travel 10 times farther between crashes than the average human driver. The more valid comparison - using airbag-involved crashes for Teslas and all other cars - finds Teslas using the driver-assistance systems travel about three times farther between crashes where airbags deployed, according to an analysis performed for Reuters by Marco Benedetti, an assistant research scientist at the University of Michigan Transportation Research Institute and a former NHTSA statistician. Two other traffic-safety researchers vetted Benedetti's calculations and agreed with the findings. But that doesn't mean FSD is actually three times safer than the average driver, Benedetti said, because of several other flaws in Tesla's methodology. Tesla tweaked its approach in November to include only data for vehicles using FSD and exclude those with Autopilot. Including Autopilot had increased Tesla's claimed miles between crashes because it's a less sophisticated system intended only for highways - where cars rack up miles and crash far less frequently than on urban streets. The company, however, continues to use the flawed airbag-crash comparison on its website to claim FSD is seven times safer than the average human driver, or about 85% safer expressed as a percentage change. Several other flawed measurements employed by Tesla cast doubt on whether FSD is any safer at all, Reuters found. The automaker, for instance, doesn't consider vehicle age when comparing the crash rate for its cars to the national rate. Tesla compares its vehicles - which are just 4.1 years old on average, according to S&P Global Mobility data - against all U.S. vehicles, which have an average age of 12.8 years. That skews the results, 10 safety researchers told Reuters, because almost all automakers have more recently started offering groundbreaking safety features, including blind-spot monitoring and automatic emergency braking, across their lineups. Tesla also reduces its crash tally by only counting wrecks that happen either with FSD switched on or within five seconds of the feature being turned off. The U.S. government, by contrast, requires automakers to report crashes occurring within 30 seconds of an advanced driver-assistance system being deactivated. Tesla says FSD could save more than 32,000 lives and prevent more than 1.9 million injuries annually. Some traffic-safety researchers called those figures meaningless because they are based on the unrealistic assumption that every U.S. vehicle, including freight trucks and crash-prone motorcycles, would be replaced by an FSD-enabled Tesla car - and that every Tesla car is, in fact, at least seven times safer than the one it replaces. WAYMO'S MORE RIGOROUS APPROACH The premise of Tesla's safety statistics is also flawed because FSD isn't a truly autonomous system, 10 traffic-safety researchers said. Tesla isn't comparing its technology to human drivers, as executives say. Instead, the automaker is comparing the average human driver to another average human - one driving a Tesla using FSD. Tesla also fails to consider that these drivers can turn FSD on and off - and research shows motorists often avoid using advanced driver-assistance systems in complicated traffic situations where the tech feels unsafe to them. Tesla's own data shows FSD is used mostly on highways. Alphabet's Waymo, by contrast, compares its fully driverless robotaxis, now deployed in 11 U.S. metropolitan areas, to human-driven vehicles in similar conditions. Waymo takes a more rigorous approach than Tesla, examining crash data in markets where it operates and adjusting for the types of roads and neighborhoods its robotaxis traverse. Waymo focuses on specific crash rates - such as those with airbag deployments or serious injuries - for both its cars and human-driven cars in the same markets. "We've got to be really careful with the language we use," said John Scanlon, a Waymo safety researcher. "You need very specific research questions and very specific conclusions." Waymo also points out shortcomings in its data and collaborates with outside researchers to publish its safety statistics in peer-reviewed journals. Tesla, by contrast, seeks no peer review and publishes only top-line statistical safety claims while keeping its underlying crash data for Tesla cars secret. VIDEOS OF TESLAS STRIKING DOGS, CATS AND DEER Inside Tesla, data labelers get an unvarnished view of FSD safety. Three former employees described several videos showing Teslas failing to recognize animals and striking them at speed - without braking. Five former employees said specific teams focused on FSD's problems recognizing school buses. That's a concern raised by a technology-safety group called the Dawn Project, which aired ads during the 2023 and 2024 Super Bowls showing videos of FSD-enabled Teslas failing to stop for buses with stop signs and flashing lights. Two former employees said they saw similar video clips inside Tesla. Five former data labelers described a harried, disjointed work environment, with priorities shifting based on directives from Musk and FSD engineers. The data-labeling unit struggled with chronic turnover because of the monotonous work and generally low pay, they said. Tesla higher-ups often launched new projects in reaction to news reports or social media posts showing FSD making mistakes, four former employees said. One described an effort to address how sunlight could obscure cars' exterior cameras. That was prompted by a social-media video showing how light reflecting off a passenger's watch blinded one of the cameras, shutting down FSD. Another effort on railroad crossings followed news reports about FSD-driven Teslas failing to stop at them. FSD clips also regularly showed speeding, five of the employees said, which engineers and others up the chain treated as a low-priority problem. One employee said labelers saw Teslas regularly exceeding speed limits by 20 to 30 miles per hour after the automaker introduced an FSD "Mad Max" mode enabling more-aggressive driving. Another labeler reported seeing an FSD-piloted vehicle traveling 60 mph in a 25-mph zone. BEHIND THE CURTAIN OF TESLA'S PUBLIC ROBOTAXI DISPLAYS As Tesla employees struggled to train FSD, Musk touted Tesla's self-driving capabilities in October 2024 in a flashy robotaxi unveiling at the Warner Bros. studio lot near Los Angeles. The invite-only crowd cheered as Musk gestured to about 20 prototypes of the two-door "Cybercab," which has no steering wheel or pedals, crawling around the studio. "The cars are just going by, with no people," he said. Musk has said Tesla's software is designed to work anywhere, navigating unfamiliar landscapes in real time. But for weeks preceding the Cybercab event, staff tested the prototypes every night from 6 p.m. until dawn, collecting video of the route the cars would follow at the launch, according to two former data-labeling employees. Labelers spent hundreds of hours annotating curbs and road markings on the video to prevent embarrassing incidents, the employees said. Waymo performs such mapping on a large scale before launching in specific cities - an approach that Musk has repeatedly dismissed as too costly and slow. Musk in 2024 derided Waymo's "very localized solutions" as "quite fragile." After the Warner Bros. event, Musk declared on a January 2025 earnings call that Tesla would be launching robotaxis in June 2025 in Austin. He touted the technology as a "generalized AI solution" that didn't require "high-precision maps of a locality." For months before the Austin launch, however, Tesla extensively filmed features in a limited robotaxi zone to map the area, capturing stop lights, road signs and other features. Data labelers annotated that video to ensure the software could handle challenging scenarios, including passenger pickup and responding to emergency vehicles, according to two employees with direct knowledge of the matter. The Utah data-labeling staff, three of the employees said, doubled in the half-year before the Austin launch to about 300 workers. The department, they said, worked primarily on projects to make the carefully controlled Austin test go smoothly. As Tesla data labelers prepared for the rollout, the software was still erratic, two of the employees said. With each FSD update, some driving behaviors improved. Others worsened. In the Utah office, two large screens displayed statistics on miles between driver interventions for FSD - a key autonomous-driving safety metric. "It would go up and down like the stock market" with no consistent improvement, one of the former employees said. The vehicles hit the streets with two sets of human safety monitors available to grab control: one sitting in the front passenger seat, and others watching remotely. In Utah, labelers could see on videos when the remote monitors took over the vehicles. One former employee said the Austin routes were designed for a limited area so the cars' software could be trained extensively on specific maneuvers on particular streets. "It was like, 'OK, we trained a car'" to operate in a restricted zone, the person said. "You can't get creative outside of that." Four of the sources said scaling up safely could take years. In July, a month after the Austin robotaxi launch, Musk predicted the service would expand to serve half the U.S. population by the end of 2025. In January, Musk falsely claimed Tesla operated 500 "robotaxi vehicles" in Austin and the San Francisco Bay Area, adding he expected that to "double every month" on an "exponential curve." Musk has said Tesla operates a "robotaxi service" in the Bay Area when it in fact only operates a ride-hailing service under a state permit, typically used by chauffeurs, that requires a human driver. In reality, nearly a year after the Austin launch, Tesla still operates only about 50 robotaxis there, according to a recent slide presentation by city officials. The vehicles traverse a limited and carefully mapped zone, three of the sources said. Some still have human safety monitors in the front passenger seat, based on recent observations by a Reuters reporter. In April, Tesla said it was rolling out robotaxis in Dallas and Houston, alongside maps showing the serviced areas. Reuters reporters who recently tested the service in both cities found long wait times and erratic availability. On three occasions when a reporter managed to get a ride in Dallas, the robotaxi wouldn't drop him at his downtown destination within Tesla's advertised service area. Each time, it left him about a 15-minute walk away. Reporting by Chris Kirkham in Los Angeles and Rachael Levy in Washington.

Former Tesla employees say full self-driving is nowhere near as capable as Elon Musk claims
Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. In brief: Tesla's Full Self-Driving software is still struggling with basic driving tasks, based on interviews with former employees who reviewed internal training footage and data. Their accounts, along with an analysis of Tesla's safety claims, suggest the technology is not as close to full autonomy as the company has publicly indicated. The findings also raise questions about how Tesla measures and markets the system's safety. Inside a data-labeling office in Utah, hundreds of workers review footage captured by Tesla vehicles running FSD. The videos are used to train the company's neural networks, with staff tagging everything from routine driving behavior to critical failures. Former employees said those clips frequently showed the system making mistakes, including failures to respond to emergency vehicles, missed hazards, and last-second driver interventions. Some of the footage was more serious. Workers described videos of Teslas striking animals or failing to slow down in time to avoid potential collisions with pedestrians. "We have all seen it fail," one former labeler told Reuters. Another said he wouldn't ride in a Tesla robotaxi "if you f---ing paid me." A former self-driving engineer who reviewed crash data for years was equally direct: "Definitely," the engineer said, "don't trust Elon on this." Tesla relies on a camera-based system trained on real-world driving footage rather than lidar or detailed pre-mapped environments. The goal is to build a generalized AI model capable of handling any condition without prior knowledge of the area. But former workers said the system still has trouble with core perception and decision-making tasks, especially in more complex scenarios. Those gaps have led to more targeted behind-the-scenes preparation, especially ahead of public demonstrations. Before Tesla's robotaxi pilot in Austin and a 2024 event at Warner Bros. studios, teams spent weeks collecting and annotating video from specific routes. Workers manually labeled lane markings, curbs, and traffic signals to help the system navigate those environments more reliably. That level of route-specific tuning contrasts with Tesla's public messaging. CEO Elon Musk has described FSD as a "generalized AI solution" that does not require the high-definition maps used by competitors, which he has called "quite fragile." Former employees, however, said Tesla's most controlled demonstrations depended on detailed, localized preparation that would be difficult to scale. The company has also promoted FSD as significantly safer than human driving, citing figures such as "10x safer" and "85% less crashes." A review of Tesla's methodology, supported by traffic-safety researchers, found that those claims rely on comparisons that are not directly equivalent. Reuters screen grabs from a Full Self-Driving demonstration video on Tesla's website show the technology navigating a range of driving situations. Image credit: Reuters Tesla, for example, counts crashes involving airbag deployment in its own vehicles but compares them with broader federal crash data, which includes less severe incidents. When comparable data is used, the gap narrows significantly. Even then, researchers said the comparison does not isolate the system's performance, since drivers can choose when to use FSD and often disengage it in more challenging situations. Other factors further complicate the analysis. Tesla only counts crashes that occur while FSD is active or within five seconds of disengagement, while federal standards use a 30-second window. The company also compares its relatively new vehicles - averaging about four years old - to a much older US fleet. Inside Tesla, progress on the system has been uneven, according to former employees. Metrics such as how often drivers need to intervene can fluctuate with each software update. "It would go up and down like the stock market," one worker said. The company's robotaxi rollout reflects those limitations. In Austin, Tesla operates a small fleet within a defined, heavily trained service area, with human oversight still in place. Expansion into other Texas cities has been inconsistent, with reports of long wait times and vehicles failing to reach intended destinations within the advertised service zones. Overall, the accounts from inside Tesla and the review of its safety data point to a system that can handle many routine driving situations but still struggles with edge cases. For now, Tesla's push toward full autonomy continues to rely heavily on human input - both from drivers and from the workers training the AI behind the scenes.

The people who trained Tesla's self-driving AI won't ride in it
A Reuters investigation found 7 of 9 Tesla data labelers wouldn't ride in FSD. They routinely saw the system speeding and failing on camera. Reuters interviewed nine former Tesla data labelers and a former self-driving engineer about their views on Tesla's Full Self-Driving mode. Seven of the nine data specialists said they would not ride in a Tesla operating on FSD. One said they would not ride in a Tesla robotaxi "if you f**king paid me." "We have all seen it fail," one insider told Reuters. The former self-driving engineer concurred: "Definitely don't trust Elon on this." They were referencing Musk's declaration that Tesla's vehicles are ready for "safe unsupervised" rides. The data labelers' job was to comb through hours of FSD footage and train the vehicle's software to avoid past mistakes. They had direct access to terabytes of proprietary driving data. At least five told Reuters they routinely saw clips of Teslas driving above the speed limit while operating on FSD. The speeding issue was treated as a low priority by engineers and managers. Edge-case problems, like unusual road configurations or rare lighting conditions, received more attention. Routine speeding, which affects every drive and every road, was deprioritised. The investigation comes as Tesla has expanded FSD availability to new markets. Tesla confirmed FSD availability in China last week, though it remains unclear whether mainstream consumers can yet activate the system. The FSD (Supervised) system is classified as Level 2, requiring constant driver attention. A fully autonomous unsupervised version is being trialled only on a fleet of robotaxis in Austin, Texas. Recent months have produced a series of FSD-related incidents. Teslas operating on FSD have driven into lakes, off bridges, and into the path of oncoming trains. These are the incidents that reached media coverage. The data labelers' testimony suggests the internal footage contains a far larger catalogue of failures. The gap between Musk's claims and the system's performance has been a persistent issue. Musk has promised fully autonomous driving repeatedly since 2016. Each deadline has passed without delivery. The company's robotaxi service in Austin operates in a geofenced area with safety drivers available remotely. Waymo's flood-related shutdowns this month demonstrated that even the most advanced autonomous driving systems have failure modes in routine conditions. Tesla's approach differs fundamentally from Waymo's: camera-only perception versus multi-sensor fusion, and a consumer vehicle repurposed for autonomy versus a purpose-built robotaxi. The data labeler testimony is significant because these workers are the closest to the raw performance data. They do not see marketing materials or earnings call projections. They see hours of video showing exactly how the software behaves on public roads. Seven of nine would not ride in the product they helped build. Tesla did not respond to Reuters' request for comment. The company has previously said that FSD (Supervised) requires active driver supervision and that its safety statistics show the system performs better than human drivers on a per-mile basis. The former engineer Reuters interviewed disputed those statistics. The investigation raises a question that Tesla's regulatory filings and marketing do not address: if the people who train the AI do not trust it, why should the people who ride in it?

Tesla's own AI trainers don't trust 'Full Self-Driving' or its safety stats, Reuters finds
A major Reuters investigation published today reveals that Tesla's widely touted "Full Self-Driving" safety statistics are built on deeply flawed methodology -- and that the company's own data labelers, the workers who train the AI system, don't trust the technology to drive them. The report, based on interviews with nine former Tesla data labelers, a former self-driving engineer, and 11 traffic-safety researchers, paints a damning picture of the gap between Tesla's safety marketing and the reality of its autonomous driving program. Tesla's safety stats inflated by a factor of 3 We've been calling out Tesla's misleading FSD safety claims for a while now, and the Reuters investigation confirms the core problem with hard data. Tesla CEO Elon Musk and other executives have repeatedly claimed that "Full Self-Driving" is up to 10 times safer than human drivers. Tesla CFO Vaibhav Taneja first made this claim last July, and Tesla Board Chair Robyn Denholm repeated it at a November shareholder meeting. Musk himself displayed a chart at that meeting claiming "85% less crashes." Reuters found that a central comparison error inflated Tesla's claimed safety level by a factor of three. Tesla counted crashes where airbags deployed in its own vehicles, then compared that number to federal data that includes all crashes requiring a tow truck -- a far less severe threshold. Tow-truck crashes often don't involve airbag deployments at all. The critical point: the federal data Tesla used already included airbag-deployment crashes as a separate category. Tesla could have made a valid apples-to-apples comparison but chose not to. When University of Michigan researcher Marco Benedetti performed the correct comparison -- airbag crashes for Teslas versus airbag crashes for all vehicles -- the result dropped from "10 times safer" to roughly three times farther between crashes. And even that figure is unreliable because of additional methodological problems, including the massive age gap between Tesla's fleet (4.1 years average) and the overall U.S. fleet (12.8 years). As Carnegie Mellon professor Phil Koopman put it: "It's like saying: 'My jet airplane is faster than your World War II bomber.' Yeah, so, what's your point?" Ten of the 11 traffic-safety researchers who reviewed Tesla's methodology for Reuters said the statistics amounted to misleading marketing rather than a serious safety investigation. 'Don't trust Elon on this' Beyond the statistics, the Reuters report reveals what Tesla employees actually think about the technology they help build. Seven of the nine former data labelers told Reuters they wouldn't trust FSD to drive them. One said he wouldn't ride in a Tesla robotaxi "if you fucking paid me." A veteran self-driving engineer who reviewed Tesla crash data for years called the company's safety claims "bullshit" and said: "Definitely, don't trust Elon on this." The data labelers, based primarily in a Utah office, review video footage from the eight exterior cameras on Tesla vehicles using FSD. They described regularly seeing FSD fail at basic tasks: pulling over for emergency vehicles, giving motorcyclists enough space, braking on freeway off-ramps, and avoiding construction zones. In one incident, a Tesla drove into a construction zone and nearly struck workers. A specialized team in Palo Alto, known internally as the "trauma team," focused specifically on near-misses with pedestrians. Former employees described seeing clips of FSD-piloted Teslas nearly hitting children and failing to recognize pedestrians in crosswalks. The report also details FSD regularly exceeding speed limits by 20 to 30 mph after Tesla introduced a "Mad Max" mode for more aggressive driving, with one labeler reporting an FSD vehicle traveling 60 mph in a 25-mph zone. The robotaxi mapping that undermines Musk's key claim One of the most significant findings in the Reuters investigation is how Tesla extensively mapped its robotaxi operating zones before public launches -- directly contradicting Musk's central claim that Tesla's approach doesn't require the "laborious local mapping" used by rivals like Waymo. For weeks before the October 2024 Cybercab unveiling at the Warner Bros. studio lot, staff tested prototypes every night from 6 p.m. until dawn, collecting video of the exact routes the cars would follow. Data labelers spent hundreds of hours annotating curbs and road markings to prevent embarrassing incidents. The same thing happened before the Austin robotaxi launch in June 2025. Tesla extensively filmed features in the limited robotaxi zone to map stop lights, road signs, and other features. The Utah data-labeling staff doubled to about 300 workers in the six months before launch, working primarily on making the Austin test go smoothly. We've previously reported on how Tesla's robotaxi expansion looked more like a stock pump than a genuine scaling effort, and more recently that the fleet is actually shrinking rather than growing. The Reuters report now explains why scaling is so difficult: the labor-intensive safeguards Tesla deploys for each launch zone are extremely difficult to replicate broadly. Nearly a year after the Austin launch, Tesla still operates only about 20 unsupervised robotaxis there, traversing a limited and carefully mapped zone. Some still have human safety monitors in the front seat. As one former employee told Reuters about the Austin zone: "You can't get creative outside of that." A growing pile of investigations and lawsuits The Reuters report arrives at a time when Tesla faces mounting regulatory scrutiny over FSD. NHTSA currently has four active investigations into FSD and Autopilot, including a probe into dozens of cases where FSD ran red lights or turned into oncoming traffic, and an investigation into whether Tesla's 2023 Autopilot recall was sufficient. Tesla was also hit with a $243 million verdict after an Autopilot crash in Florida killed a 22-year-old woman, and the company has struggled to turn over FSD traffic violation data to NHTSA investigators. Musk told shareholders in November that Tesla would soon let drivers text while using FSD. Six months later, the company hasn't done so, and its own FSD website continues to warn: "Currently enabled features require active driver supervision and do not make the vehicle autonomous." Electrek's Take None of this is surprising to anyone who has been paying close attention. We've been documenting FSD's pattern of repeated safety claims that don't hold up, version after version, year after year. What the Reuters investigation adds is the internal perspective -- and it's devastating. The fact that Tesla's own data labelers, the people who see FSD's performance every single day, overwhelmingly don't trust the system to drive them should tell you everything you need to know about the gap between Musk's promises and reality. The statistical methodology issue is particularly damning because it's not a subtle error. Tesla had access to the correct comparison data and chose to use a metric that inflated its safety claims by 3x. That's not a choice you make by accident. And when 10 out of 11 independent traffic-safety researchers call your safety report "misleading marketing," you have a credibility problem that no software update can fix. A growing issue is that while this is happening, FSD is undoubtedly getting better -- at least for vehicles equipped with HW4. It's getting so good that more people are becoming complacent with it, which is where it becomes increasingly dangerous. While it makes significantly fewer mistakes than it did a year ago, if the drivers are feeling so confident that they are not paying attention when those few mistakes arise, it becomes more dangerous. I don't think Tesla is doing enough to address this complacency problem. If you're a Tesla owner concerned about rising electricity costs, powering your EV with home solar is one of the smartest ways to lock in savings. With electricity rates climbing nearly 10% last year, home solar protects you against future rate increases. And with lease and PPA options, you can go solar with zero upfront cost and start saving immediately. If you want to find the best deal, check out EnergySage. It's a free service with hundreds of pre-vetted installers competing for your business, so you save 20 to 30% compared to going it alone. No sales calls until you pick an installer.

A Reuters investigation exposes serious gaps between Tesla's safety claims and reality. Seven of nine data labelers who trained the Full Self-Driving system say they wouldn't trust it to drive them. The report reveals flawed safety statistics that inflate FSD's performance by a factor of three, while former employees describe regular failures with basic driving tasks and extensive route mapping that contradicts Elon Musk's claims about Tesla's autonomous driving approach.
A Reuters investigation has uncovered troubling revelations about Tesla Full Self-Driving technology, with the people who know it best refusing to trust it with their lives. Seven of nine former Tesla employees who worked as data labelers told Reuters they would not ride in a vehicle operating on FSD
1
. One former worker was emphatic: they wouldn't ride in a Tesla robotaxi "if you f---ing paid me"2
. A former self-driving engineer who reviewed crash data for years offered equally stark advice: "Definitely, don't trust Elon on this"3
.These Tesla's AI trainers, known as data labelers, spend their days in a Utah office reviewing footage captured by Tesla vehicles using FSD. Their job involves annotating incidents of good and bad driving, escalating problems to engineers working to improve the autonomous driving system
1
. What they see regularly concerns them: videos of Teslas striking animals, failing to slow down in time to avoid potential collisions with pedestrians, and near-misses with children playing in the street2

Former Tesla employees describe a self-driving technology that continues to struggle with fundamental driving tasks. The system has shown repeated failures to respond appropriately to emergency vehicles, missed hazards, and required last-second driver interventions
2
. Data labelers reported seeing FSD-piloted vehicles fail at basic tasks including pulling over for emergency vehicles, giving motorcyclists enough space, braking on freeway off-ramps, and avoiding construction zones4
.At least five former employees told Reuters they routinely saw clips of Teslas driving above the speed limit while operating on FSD
3
. After Tesla introduced a "Mad Max" mode for more aggressive driving, the system regularly exceeded speed limits by 20 to 30 mph, with one labeler reporting an FSD vehicle traveling 60 mph in a 25-mph zone4
. Troublingly, the speeding issue was treated as a low priority by engineers and managers, while edge-case problems like unusual road configurations received more attention .Elon Musk and other Tesla executives have repeatedly claimed that FSD is up to 10 times safer than human drivers. Tesla CFO Vaibhav Taneja first made this claim in July, and Tesla Board Chair Robyn Denholm repeated it at a November shareholder meeting where Musk displayed a chart claiming "85% less crashes"

. However, the Reuters investigation reveals these misleading safety statistics are built on deeply flawed comparisons.Tesla exaggerates FSD safety by comparing crashes in FSD-piloted vehicles that triggered airbag deployments to federal crash data that includes far less-severe accidents requiring only a tow truck
1
. When University of Michigan researcher Marco Benedetti performed the correct comparison—airbag crashes for Teslas versus airbag crashes for all vehicles—the result dropped from "10 times safer" to roughly three times farther between crashes4
. This means a central comparison error inflated Tesla's claimed safety level by a factor of three.Ten of 11 traffic-safety researchers who reviewed Tesla's methodology for Reuters said the statistics amounted to misleading marketing rather than a serious safety investigation
1
. The company also compares its relatively new vehicles—averaging about four years old—to the much older U.S. fleet averaging 12.8 years2
. Phil Koopman, a Carnegie Mellon University engineering professor and autonomous-vehicle safety expert, explained: "Any new car is dramatically safer than a 12-year-old car. It's like saying: 'My jet airplane is faster than your World War II bomber.' Yeah, so, what's your point?"1

. The Utah data-labeling staff doubled to about 300 workers in the six months before the Austin launch, working primarily on making the test go smoothly4
.The findings raise fundamental questions about Tesla's path to full autonomy, which underpins the automaker's $1.6 trillion stock-market value
1
. Inside Tesla, progress on the system has been uneven, with metrics such as how often drivers need to intervene fluctuating with each software update. "It would go up and down like the stock market," one worker said2
.The company's robotaxi rollout reflects these limitations. In Austin, Tesla operates a small fleet within a defined, heavily trained service area, with human oversight still in place
2
. Tesla confirmed FSD availability in China last week, though it remains unclear whether mainstream consumers can yet activate the system3
. The FSD (Supervised) system remains classified as Level 2, requiring constant driver attention .The testimony from data labelers carries particular weight because these workers see raw performance data rather than marketing materials or earnings projections . They witness hours of video showing exactly how the software behaves on public roads. If the people who train the AI don't trust it, the investigation asks, why should the people who ride in it? Tesla did not respond to detailed questions from Reuters for this report
