Why Is Tesla (TSLA) Stock Down 5.92% Today, Sep 4? Cybercab Concerns and Federal Safety Review Pressure Shares

Tesla shares fell 5.92% after the Austin Cybercab rollout underdelivered on near-term commercial details (pricing, scale, utilization) and reports of early operating issues triggered a sell-the-news reassessment. Adding pressure, NHTSA opened an audit into Tesla's self-certification process for vehicles lacking conventional controls, increasing regulatory and timing uncertainty for autonomous deployment. Near-term trading focus shifts to rollout metrics and regulatory updates rather than further product hype.
