NHTSA examines Tesla's Cybercab self-certification after the Sept. 3 launch event

NHTSA opened an audit of the process and technical data Tesla relied on when it self-certified the Cybercab as compliant with federal safety standards. The query covers an estimated 1,000 vehicles. The probe landed the day after an invitation-only Cybercab event that investors found underwhelming, and Tesla shares fell sharply in the next session.
