TLDR
- NHTSA sent Tesla a letter demanding answers about its Cybercab self-certification by September 30.
- The Cybercab launched commercially in Austin, Texas on September 3 with no steering wheel, pedals, or mirrors.
- NHTSA wants to know if the Cybercab can be operated by a human driver using temporary controls.
- Tesla stock was up just 0.1% in premarket trading at $357, brushing off the inquiry.
- Tesla has been down 21% year-to-date and 13% over the past 12 months through Tuesday.
The U.S. National Highway Traffic Safety Administration has put Tesla on the clock. The regulator sent a formal letter to Tesla on Tuesday, demanding answers about how it self-certified its Cybercab robotaxi, with a deadline of September 30.
Tesla began commercially deploying a small number of Cybercabs in Austin, Texas on September 3. The two-seat vehicle has no steering wheel, no brake pedal, no accelerator pedal, and no mirrors. Tesla self-certified the vehicle as compliant with all Federal Motor Vehicle Safety Standards before deployment.
NHTSA opened its investigation shortly after, saying it needed to examine the process and technical data Tesla used to certify the Cybercab. Tuesday’s letter is a formal step within that existing investigation.
What NHTSA Is Asking
The regulator’s questions are detailed. It wants to know whether the Cybercab is capable of being driven by a human using temporarily attached controls. It also asks about maximum speed, geographic limits, time-of-day restrictions, and whether the vehicle’s touchscreen gives occupants any ability to move the vehicle.
NHTSA also wants to know whether any temporary human controls were part of Tesla’s original certification basis. That is a pointed question, given that existing federal standards still require steering wheels, brake pedals, and mirrors for vehicles operating on U.S. roads.
The current rules allow NHTSA to grant exemptions for up to 2,500 vehicles per manufacturer per year. Amazon’s Zoox unit received such an exemption in July for limited commercial deployment of its own steering-wheel-free robotaxi.
Where the Stock Stands
Tesla stock barely moved on the news. It was up 0.1% in premarket trading Wednesday at $357, roughly flat compared to where it traded when the Cybercab launched in Austin earlier this month.
Through Tuesday’s close, TSLA was down 21% year-to-date and down 13% over the past 12 months.
Investors have long bet that Tesla’s autonomous vehicle ambitions are a core part of its trillion-dollar valuation. The Cybercab and robo-taxi fleet expansion are central to that story.
Tesla and other robotaxi operators, including Alphabet’s Waymo, have backed the Trump administration’s push to change federal regulations so autonomous vehicles no longer need human controls. Critics argue exemptions should not be granted until safety is proven.
NHTSA investigations can lead to recalls. Past Tesla self-driving probes have resulted in required software modifications. Tesla has not responded to requests for comment on this latest letter.
