Incident Description: I was driving on the highway using Tesla Full Self-Driving (FSD) / FSD Supervised at approximately 65+ mph. Traffic conditions were moderate, and weather and visibility conditions were clear. While FSD was actively engaged, my phone began ringing. As I briefly attempted to silence the ringing phone, the FSD system unexpectedly disengaged/canceled during highway driving. I did not receive sufficient audible warning, advance notification, or adequate transition time to safely assume full manual control of the vehicle. There was no meaningful cushion time for driver response before vehicle behavior changed. The disengagement occurred abruptly and created an immediate dangerous situation at highway speed. The sudden transfer of control, without sufficient warning or response time, significantly reduced my ability to react safely. At the time of the incident: - My attention had been on the roadway prior to the phone ringing - I was monitoring the vehicle as required under FSD Supervised - My hands were near the steering wheel - There was no construction, lane merge, or unusual road condition nearby Immediately following the disengagement, the vehicle suddenly drifted and braked, resulting in a collision with the curb/barrier area near the highway bridge. Fortunately, no other vehicles were involved and no secondary collision occurred. I am requesting that Tesla investigate: - FSD disengagement behavior - Warning timing and driver alert mechanisms - System logs and telemetry data - Whether the vehicle generated internal safety/event reports at the time of the incident - Whether the disengagement and transition-to-driver behavior complied with Tesla’s intended safety protocols Relevant evidence preserved: - Tesla dashcam footage - Photos of vehicle damage and scene - Time and location information - Vehicle data request pending
