NHTSA opens investigation into Tesla Cybercab certification process

NHTSA has opened an investigation into Tesla's Cybercab, focusing on the technical data and certification process used, given federal rules require steering wheels and pedals unless exempted, and Tesla has not sought an exemption. The probe could delay or complicate Tesla's autonomous vehicle ambitions, posing regulatory and reputational risk. The outcome is uncertain, but the investigation signals heightened regulatory scrutiny of Tesla's self-driving technology.
