Tesla’s robotaxis are moving in reverse

Tesla’s budding “Robotaxi” network drove fewer miles for paying customers in the second quarter than it did in the first, according to a chart the company released on Wednesday.

The quarter-over-quarter decline runs counter to Tesla’s rhetoric and actions in the past year. Tesla has staked much of its future on the idea of a massive, low-cost, cash-generating Robotaxi fleet — or going “balls to the wall for autonomy,” as CEO Elon Musk framed it in 2024. The quarterly step-down in Robotaxi miles also comes amid weakening profits in Tesla’s core businesses, which underperformed Wall Street’s expectations, according to figures released Wednesday. Tesla’s stock plunged more than 13% in early trading on Thursday.

At a passing glance, the chart appears to show steady growth in paid Robotaxi rides between August 2025 and June 2026. But the numbers displayed are cumulative, and when broken down by quarter, they show that Tesla’s Robotaxi fleet of Model Y SUVs carrying paying passengers covered around 1.1 million miles in the first quarter. That fell to roughly 700,000 miles in the second quarter, a decline of about 36%.

That’s despite the fact that the company has expanded its nascent operation to six cities across Texas and Florida, with a mix of unsupervised and supervised vehicles.

It’s likely Tesla is counting the paid miles driven in the San Francisco Bay Area, too, even though these branded Robotaxis don’t have the state-required permits to operate autonomously and also have a safety driver behind the wheel. Tesla has referred to that operation as part of its “Robotaxi coverage.”

The decline in miles driven also comes as Tesla made a striking admission on a conference call Wednesday about its second-quarter results. In response to a question about how slowly Tesla is scaling the Robotaxi service, Musk said the company needs to “accumulate driving data that is specific to the Cybercab” — the company’s gold, purpose-built, two-seater sedan that is expected to make up the bulk of its autonomous vehicle fleet — “before we can put a lot of them on the road.”

“Unlike, say, Model 3, Model Y, and our other vehicles where we’ve got a lot of vehicles on the road, millions of vehicles on the road, we don’t have that for Cybercab. So 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,” he said. “As we are confident about that, the number of Cybercabs in cities will increase dramatically.”
