What Happened
US vehicle-safety officials have asked Tesla to defend the certification behind its driverless Cybercab. The National Highway Traffic Safety Administration wants a written response by September 30, after Tesla put a small number of the vehicles into paid service in Austin. The agency is reviewing the data and internal process used to clear the vehicle for deployment; Tesla has not commented.
The Cybercab has no steering wheel, brake or accelerator pedal, or rear-view mirrors. Current US rules still expect that equipment unless a waiver or a completed rule change says otherwise, and the company has not secured a waiver for this rollout. Tesla started commercial service in Austin on September 3 and plans to add more vehicles.
- Can a person take control and drive a Cybercab?
- Did temporary human-driving equipment play a role in the certification basis?
- Can the touchscreen command the vehicle to move?
- What top speed applies?
- Where and during which hours may the vehicles operate?
NHTSA proposes removing the manual-brake-pedal requirement.
The agency approves an exemption petition filed by Amazon's Zoox.
Tesla begins commercial Cybercab service in Austin.
NHTSA announces an audit query into the vehicle's self-certification.
NHTSA sends detailed questions; Tesla's response is due September 30.
“NHTSA fully supports the safe development and deployment of automated vehicles. But as the federal regulator, we need to ensure that all of our laws are followed.”
The US system asks manufacturers to certify their own vehicles against federal performance rules, with NHTSA checking compliance afterward. The agency is developing eight rulemakings covering areas such as lights, wipers, mirrors and brake pedals, but the existing requirements remain in force for now. The audit also asks if Tesla's compliance process treated some conventional FMVSS provisions as irrelevant to an automated vehicle.

Why this matters
Tesla's Austin robotaxi service is operating on the company's own certification rather than a regulator's prior approval. NHTSA's review could influence whether the service expands and how quickly the US rewrites rules for vehicles without conventional driver controls.
