On June 23, 2025, one day after Tesla’s robotaxis started carrying passengers in Austin, the National Highway Traffic Safety Administration (NHTSA) confirmed it had reached out to the company. The trigger: a series of videos circulated over the weekend showing the vehicles speeding, driving into the oncoming lane, and braking suddenly — twice — near police cars parked along a South Austin road.
It was the first public confirmation that the regulator was acting on the new service. For developers and product teams in autonomy, the episode is worth reading on three levels: what tools a regulator actually has under the US self-certification regime, how many operational details Tesla is still withholding, and how capital markets reacted to a safety controversy — Tesla stock rose 8% the same day.
The regulator steps in
Bloomberg first reported the NHTSA contact; TechCrunch then confirmed it directly with the agency. NHTSA said it was “in contact with the manufacturer to gather additional information” and would take any actions required to protect road safety. CNBC quoted a related statement noting the agency “is aware of the referenced incidents.” CNBC also reported that Tesla’s VP of vehicle engineering, Lars Moravy, and regulatory counsel Casey Blaine did not respond to requests for comment. In other words, nearly everything known about the robotaxi operation’s early days comes from outside observers’ videos rather than Tesla’s own disclosures. Notably, this information-gathering targets the new robotaxi service, not Tesla’s existing consumer FSD system — the agency treats the two as separate matters.
The incidents on video
Three kinds of behavior were captured. First, Ed Niedermeyer — author of “Ludicrous” — filmed a robotaxi braking suddenly twice near police vehicles parked in driveways adjacent to the road, once in live traffic. Second, wrong-way driving: one vehicle was recorded swerving into the oncoming lane. Third, speeding: footage compiled by TechCrunch showed cars traveling over the limit. CNBC also noted the pilot had run only in daylight and good weather — the videos surfaced under the most favorable operating conditions available. None of these amounted to a serious crash, but under an operating model with no driver and only a safety monitor in the front passenger seat, each video points at the same question: where exactly are the boundaries of this system?
Self-certification: the regulator’s toolbox
NHTSA’s statement also explained the limits of its role. The agency does not pre-approve new technologies; manufacturers self-certify that vehicles meet federal safety standards, and NHTSA’s lever is investigating potential safety defects after the fact, acting as warranted. That is why the response here is “gathering information” rather than a shutdown or a fine — and it is the same defect-investigation pathway behind the ongoing FSD Supervised probe. For anyone building in this space, it is a structural lesson in US autonomy regulation: the compliance burden sits on self-certification and post-hoc accountability, not on a pre-launch permission process.
The stock rose 8% anyway
The market reaction is the strangest part. On the same day NHTSA confirmed contact — Monday, June 23 — Tesla shares rose 8%, signaling that investors weighed the launch itself more heavily than the safety debate. The market is pricing the launch as an option, not as a shipped product — a stance nearly immune to safety headlines. CNBC’s roundup also frames the competitive baseline: the pilot is roughly 10-20 Model Ys, running in daylight and good weather only, serving invited users with a human safety monitor in the passenger seat. By comparison, Waymo has surpassed 10 million paid trips, and Chinese rivals including Baidu’s Apollo Go and WeRide already run commercial fleets. The gap between Tesla’s decade of autonomy promises and this launch remains wide.
What to watch: two separate inquiry tracks
Two threads need to be tracked separately. The first is this new information-gathering contact on the robotaxi service, which has not yet escalated into a formal investigation. The second is NHTSA’s existing defect probe into the consumer FSD Supervised system, opened after injury and fatal crashes, which continues in parallel. Tesla, meanwhile, still has not explained how its “unsupervised” FSD version differs from the consumer product. The things to watch: whether the incident videos keep coming, whether NHTSA upgrades from contact to a defect investigation, and whether Tesla discloses more operational data under pressure.
