The National Highway Traffic Safety Administration launched an investigation into Tesla’s driverless taxis a day after their Austin debut, as the company’s stock fell 6% to $602 amid regulatory scrutiny over safety compliance.
Tesla’s self-driving Cybercabs, which lack steering wheels, mirrors, and brake pedals, faced immediate regulatory scrutiny after their launch in Austin, Texas. The National Highway Traffic Safety Administration (NHTSA) announced an inquiry into whether the vehicles met federal safety standards, citing concerns about the company’s self-certification process. The probe followed a stock gain on Thursday, which was erased by a 6% drop on Friday as investors reacted to the regulatory action.
Regulatory Scrutiny of Driverless Taxis
The NHTSA’s investigation focuses on whether Tesla properly self-certified the Cybercabs as safe for public roads, a process the agency says will involve examining the process and technical data
used by the company. Unlike traditional vehicle certifications, the Cybercabs represent a significant departure from conventional design, raising new safety questions. The agency noted that automakers typically self-certify new models, but investigations are rare unless regulators suspect rule violations.
The probe echoes past regulatory challenges faced by rival robotaxi services. Tesla, however, has faced multiple ongoing investigations into its self-driving software, including a probe into its role in crashes involving pedestrians and vehicles in low-visibility conditions. The company is also grappling with a $240 million liability stemming from a 2019 Miami crash it was partly responsible for, which it plans to appeal.
Elon Musk’s vision for the Cybercabs includes integrating them into Tesla’s existing ride-hailing network, which has operated robotaxi services in Austin for over a year. The vehicles, which lack manual controls that passengers could use to take over in an emergency, are designed to operate without manual controls, a feature that regulators are now scrutinizing for potential risks.
Financial Fallout and Market Reaction
Tesla’s stock fell sharply after the NHTSA announcement, reversing gains from the previous day’s launch event. The drop came despite Musk’s efforts to frame the Cybercabs as a transformative step in transportation.
The market’s reaction underscored investor skepticism about Tesla’s ability to scale its robotaxi ambitions.
Investors are also wary of the operational costs associated with maintaining a robotaxi fleet. This contrast highlights the challenges Tesla faces in balancing innovation with economic viability.
Ongoing Investigations and Safety Concerns
The NHTSA’s probe is part of a broader regulatory push to assess the safety of autonomous vehicles. The agency has received 58 reports of incidents involving Tesla’s full self-driving (FSD) technology, including 14 crashes and 23 injuries. These cases involve vehicles operating in self-driving mode, with drivers reporting that they often had no warning that the vehicle was about to do something unexpected. The Associated Press cited these figures in its coverage of the investigation.


Tesla’s safety record has drawn scrutiny beyond the NHTSA. The company is facing lawsuits over a Cybertruck crash that killed Krysta Tsukahara last year, and its FSD software has been linked to multiple incidents involving red-light violations and wrong-side driving. The NHTSA’s audit of the Cybercabs could set a precedent for how regulators evaluate autonomous vehicles, given the lack of established guidelines for steering-wheel-free designs.
As the investigation unfolds, the outcome could shape the future of Tesla’s robotaxi ambitions. The company has pledged to transform the way people travel, but regulators and investors alike are waiting to see if its vision aligns with safety and financial realities. For now, the Cybercabs remain a symbol of both innovation and the complex challenges of scaling autonomous technology.
