Tesla robotaxi mileage drops 36% as Elon Musk shifts tone on autonomous ride-hailing rollout

Tesla Robotaxi Mileage Declines Despite Geographic Expansion

Tesla's autonomous ride-hailing rollout hit an unexpected snag in the second quarter of 2026, with the Tesla robotaxi fleet driving approximately 700,000 miles for paying customers—down from 1.1 million miles in the first quarter, representing a 36% decline 1

1

. The quarter-over-quarter drop contradicts the company's ambitious rhetoric about building a massive, cash-generating autonomous vehicles fleet, which CEO Elon Musk once described as going "balls to the wall for autonomy" 1

1

. This development comes as Tesla expanded its nascent operation to six cities across Texas and Florida, mixing unsupervised robotaxi operations with supervised vehicles, and potentially including paid miles driven in the San Francisco Bay Area where branded robotaxis operate with safety drivers behind the wheel 1

1

.

The mileage decline emerged from data Tesla released Wednesday during its second-quarter earnings call, where the company's stock subsequently plunged more than 13% in early trading Thursday 1

1

. At first glance, Tesla's cumulative chart appeared to show steady growth in paid rides between August 2025 and June 2026, but breaking down the numbers by quarter revealed the troubling trend in scaling autonomous driving business 1

Musk Admits Data Collection Challenges for Cybercab Deployment

During the earnings call, Elon Musk made a striking admission that represents a significant departure from Tesla's longstanding narrative about its AI-driven autonomy advantage. When questioned about the slow pace of the autonomous ride-hailing rollout, Musk explained that Tesla needs to "accumulate driving data that is specific to the Cybercab"—the company's purpose-built, two-seater autonomous vehicle expected to form the bulk of its fleet—"before we can put a lot of them on the road" 1

1

. He elaborated that unlike Model 3 and Model Y vehicles, which number in the millions on the road, Tesla doesn't have that data foundation for Cybercab 1

1

.

"We actually have to accumulate miles with Cybercabs that are retrofitted with steering wheels and acceleration and braking pedals, that kind of thing, to calibrate to the Cybercab chassis," Musk said, adding that "as we are confident about that, the number of Cybercabs in cities will increase dramatically" 1

1

. This admission breaks from years of claims that Tesla's fleet of nearly 10 million customer cars has been silently collecting data in the background to train future robotaxis, in addition to training the Full Self-Driving driver assistance software for consumers 1

Safety Concerns and Regulatory Hurdles Slow Expansion

Tesla executives framed the slow progress as a deliberate focus on safety concerns during the earnings call. Musk emphasized that while there are 30,000 to 40,000 automotive deaths per year in the United States alone that generate minimal press coverage, "if we injure even one person, it will be worldwide headline news, and regulators will immediately clamp down on our activities" 1

. He stated Tesla is "going as fast as humanly possible in scaling Robotaxi while trying to ensure that we do not harm anyone at all and ideally do not even run over a pet" 2

2

.

Ashok Elluswamy, Tesla's VP of AI, boasted that Tesla's robotaxis have had "zero notable incidents" while driving "more than 380,000 miles" without a safety operator onboard 1

1

. However, Tesla has reported 22 crashes to the National Highway Safety Administration in the year since it started trialing its service, including three crashes caused by teleoperators moving vehicles remotely and multiple instances of cars hitting objects at low speeds including curbs, utility poles, and a tow truck's bed 1

.

Regulatory risks are mounting as well. Tesla's vice president of vehicle engineering Lars Moravy acknowledged that "the stuff in New Jersey, you know, is a little bit disheartening," referring to a bill under consideration that would essentially ban robotaxis without multiple sensors like radar and lidar 2

2

. CFO Vaibhav Taneja added that "regulatory situations are different city by city" and "there are different kinks...not just on the software front, but on the operations front" that Tesla is trying to tackle 3

Waymo's Lead Widens as Tesla Struggles to Scale

The reality of Tesla's AI-driven autonomous vehicle initiative stands in stark contrast to industry leader Waymo, which drives around four million miles per week 2

2

. Tesla's total mileage after a year of operation is less than 10 percent of that figure, with paying customers having traveled just 2.5 million cumulative miles, including 380,000 miles in rides without an in-vehicle safety monitor 3

3

. Tesla's unsupervised robotaxi miles remain well below the more than 220 million autonomous miles driven by Waymo through the end of March, underscoring the significant lead Alphabet's self-driving unit holds in commercial deployment, according to Forrester analyst Paul Miller 3

.

According to the crowdsourced Robotaxi Tracker, Tesla currently has only 16 unsupervised vehicles in Austin, four in Dallas, and one in Houston 2

2

. When asked why Tesla wasn't flooding the zone in Austin where it first launched robotaxis a year ago, Elluswamy explained that "the reason we have been expanding across different cities, instead of just doubling down on a single city, is that we want to make sure that our stack is a very general one" 2

2

.

Despite the challenges, Elluswamy defended Tesla's camera-only AI approach against competitors using lidar sensors. "Historically, the so-called experts have always claimed that you need lidars, radars, HD maps, and the entire kitchen sink to drive safely," he said. "Here we show that such is not true. You can have safe, comfortable, and affordable autonomy stack with just cameras" 2

Investor Concerns Mount as Expansion Lags Promises

The slow autonomous ride-hailing rollout is spooked investor concerns, with BNP Paribas Equity Research senior analyst James Picariello calling it "an alarming decline" in a research note to clients 2

, but service areas in these cities, like Miami and Houston, remain limited to less-trafficked neighborhoods outside city centers 3

.

A year ago, Musk said the robotaxi network would expand at a "hyper-exponential rate" and be available to half the U.S. population by the end of 2025 3

3

. In an investor presentation in January, Tesla said its robotaxis would expand to seven metro areas by the end of June: Dallas, Houston, Phoenix, Miami, Orlando, Tampa and Las Vegas. Up until Tuesday, Tesla had only launched in three of those cities 3

.

Investors have valued Tesla on the promise that robotaxis and its Optimus robot will one day become its primary revenue drivers. The stock trades at more than 166 times forward earnings estimates, far above the multiples of traditional automakers and Big Tech companies 3

. The stock has fallen nearly 17% this year as of the last close 3
