On September 3, 2026, Tesla launched the commercial operation of its autonomous taxi Cybercab in Austin, Texas. This vehicle eliminated manual control devices such as steering wheels, brake pedals, accelerator pedals, and rearview mirrors, and claimed to meet federal motor vehicle safety standards. On the same day (September 4), the U.S. National Highway Traffic Safety Administration (NHTSA) announced the initiation of an investigation to review whether Tesla’s self-certification process was compliant, focusing on its technical data and the reasons for removing conventional control devices. The investigation covered approximately 1,000 vehicles. Previously, Zoox, a subsidiary of Amazon, had also been reviewed and required to apply for temporary exemptions due to similar circumstances. After this incident, Tesla’s stock price dropped significantly, with its market value decreasing by about $100 billion in a single day. Regulators stated that they would strictly review the compliance and safety of this technology, and if any concealment or false advertising was confirmed, Tesla would be fined. Currently, the market is closely monitoring the specific impact of this incident on Tesla’s future financing plans and the pace of advancing its autonomous driving business.

Cybercab had a poor start in the US; Tesla lost 600 billion overnight and also faced regulatory issues

On Thursday, Eastern Time, Tesla unveiled the production version of the Cybercab autonomous taxi in Austin, Texas. This vehicle eliminates the steering wheel, accelerator and brake pedals, and rearview mirrors. It operates based on the FSD system, with a target price of less than $30,000 and operating costs controlled at less than $0.2 per mile. After the unveiling, Tesla’s stock price plummeted upon market opening, with the maximum decline exceeding 6.2% during trading. Its market value dropped to $1.39 trillion, a decrease of about $100 billion in a single day (approximately 677.8 billion yuan). On the same day, the U.S. National Highway Traffic Safety Administration announced that it would conduct an investigation into Cybercab to verify the compliance of its certification process and whether up to 1,000 vehicles meet federal motor vehicle safety standards.

U.S. regulators investigate Tesla’s “cybertaxi” safety certification

The National Highway Traffic Safety Administration (NHTSA) announced on the 4th that it had initiated an investigation to review whether Tesla’s driverless “cybertaxis” complied with U.S. federal motor vehicle safety standards. The investigation focused on the procedures and technical data used by Tesla in safety certification, particularly in cases where the vehicles did not have standard manual control devices installed, such as brake pedals and accelerator pedals. Regulatory documents indicate that Tesla began commercial deployment of a small number of “cybertaxis” in Austin, Texas, on the 3rd, and stated that it had determined all applicable standards were met. The company also plans to gradually expand its deployment. U.S. motor vehicle safety regulation implements a manufacturer certification system; when a vehicle certified by a manufacturer is deemed potentially non-compliant with relevant standards, NHTSA has the authority to conduct an investigation.

Cybercab was caught right after it was released to service, and Tesla sent its autonomous vehicles into areas where regulations do not apply.

The National Highway Traffic Safety Administration (NHTSA) launched an investigation on September 4, requiring Tesla to prove that its Cybercab meets federal motor vehicle safety standards (FMVSS). As a vehicle designed specifically for Robotaxi, the Cybercab eliminates the steering wheel, brake pedal, accelerator pedal, and traditional rearview mirrors. The controversy centers on whether the current safety standards based on human drivers in the United States apply to this vehicle type. Previously, the Cybercab had been put into real operation in Austin, Texas, on September 3. Tesla chose to self-certify rather than apply for an exemption, arguing that some manual driving requirements do not apply to driverless vehicles. This investigation aims to determine whether the self-certification system can adapt to the new product form of fully autonomous driving and to assess the risks associated with companies setting their own regulatory boundaries.

Cybercab was reviewed the day after it went online. Why couldn’t Tesla wait any longer?

On September 4th, local time, the U.S. National Highway Traffic Safety Administration (NHTSA) announced that it would initiate an investigation into Tesla Cybercab’s self-certification of federal motor vehicle safety standards. The authorities will examine the technical data used by Tesla and the reasons why they determined that current safety standards are not applicable to this vehicle. The Cybercab attracted attention due to the removal of permanently installed brake pedals, accelerator pedal, steering wheel, and rearview mirrors. The investigation covered approximately 1,000 vehicles. Previously, Zoox, a subsidiary of Amazon, also underwent an investigation and had to reapply for temporary exemptions due to similar situations. Tesla Cybercab faced scrutiny immediately after entering commercial operation in Austin, Texas on September 3rd, reflecting the urgent need to quickly implement and fulfill its commercial commitments.
