Tesla Gets Extension to Respond to NHTSA's Cybercab Probe
NHTSA granted 30 days instead of the requested eight weeks, moving the deadline to October 30, 2026.
The National Highway Traffic Safety Administration (NHTSA) has granted Tesla a 30-day extension to respond to a Special Order regarding the Cybercab’s federal safety certification, falling short of the eight-week delay the automaker requested.
What Happened
Tesla originally sought an extension until November 20, citing the "voluminous nature of the request," but NHTSA moved the deadline from September 30 to October 30, 2026. This response is part of Audit Query 26002, opened by NHTSA on September 3 to evaluate Tesla’s basis for certifying that the Cybercab complies with all applicable Federal Motor Vehicle Safety Standards (FMVSS). The agency has posed 21 specific questions, focusing heavily on how Tesla self-certified a vehicle lacking a steering wheel, pedals, and side mirrors.
Regulators are specifically asking how the Cybercab meets rules for turn signals, mirrors, rearview cameras, and foot-operated service brakes without an exemption. While Zoox utilized an exemption process allowing up to 2,500 vehicles per year, Tesla chose to self-certify. NHTSA wants to know if temporary human controls were used during certification testing and whether passengers can move the vehicle via the touchscreen. Although NHTSA proposed dropping some manual-control requirements in June, those changes are not yet finalized, meaning current rules remain binding.
Why It Matters
The outcome of this probe could dictate the pace of the Cybercab’s expansion beyond Austin, where public rides currently take place. Tesla appears to be preparing for launches in other markets; nearly 200 Cybercabs have been spotted in Houston, and a large charging nest has been observed in Miami. However, the agency’s scrutiny of the self-certification process highlights the regulatory hurdles facing autonomous vehicles that lack traditional manual controls. If NHTSA finds Tesla’s explanations insufficient, it could stall the rollout of the purpose-built robotaxi in new cities.
The Bottom Line
Tesla must provide detailed answers to 21 regulatory questions by October 30, 2026. While Cybercab operations continue in Austin, the federal review of its safety certification remains a critical bottleneck for the vehicle’s broader commercial expansion.
