# What happened Tesla put a purpose-built autonomous vehicle, the two-seat Cybercab, into limited public rides in Austin, Texas. The Cybercab removes traditional driver controls such as a steering wheel, accelerator and brake pedals, and conventional mirrors. The National Highway Traffic Safety Administration opened an Audit Query to examine the technical and certification information Tesla used when claiming the Cybercab complies with Federal Motor Vehicle Safety Standards (FMVSS).
# Why regulators are looking Most FMVSS were written on the assumption that a human driver sits behind the wheel. Because the Cybercab intentionally omits conventional controls, NHTSA wants to know how Tesla determined which standards apply and whether Tesla's certification process and supporting data are adequate.
# What NHTSA can do Under the federal system, manufacturers certify their own vehicles meet applicable FMVSS before deploying them. NHTSA has authority to investigate compliance, request documentation, perform testing, and pursue recalls or other enforcement actions. The current action is an audit-style review focused on certification decisions rather than a defect allegation.
# How many vehicles are involved The review reportedly covers nearly 1,000 Cybercab vehicles. Public reports referenced roughly 420 autonomous vehicles registered in Texas at the time, including a smaller number of Cybercabs in service as the limited deployment began.
# Immediate impact for Tesla and the public There is no indication that NHTSA has ordered Cybercabs off the road. Opening an audit does not mean the vehicles are unsafe or improperly certified. However, Tesla may need to provide detailed explanations and records showing how it concluded certain FMVSS do or do not apply to the Cybercab's unconventional design.
# Why this matters beyond Tesla If vehicles designed without steering wheels and pedals are to operate widely, regulators and manufacturers will need clearer rules for which FMVSS still apply and how to certify fully autonomous designs. The Cybercab audit could shape how federal agencies approach certification of future purpose-built driverless vehicles.
# What to watch next
- NHTSA's audit findings and whether the agency requests tests, further documentation, or issues enforcement actions.
- Whether Tesla supplies detailed certification rationales or seeks exemptions for specific FMVSS.
- Any expansion of Cybercab deployments or public rides while the audit continues.
# Bottom line The NHTSA inquiry targets the certification process for a vehicle that removes conventional driving controls. It raises procedural and regulatory questions rather than an immediate safety recall, but the outcome could influence future certification approaches for driverless vehicles.
