On XXX, at approximately 8:10 PM PDT in [XXX], I was driving my 2025 Tesla Model 3 (VIN [XXX]) with Full Self-Driving (Supervised) engaged. While FSD was actively steering a right turn at an intersection, the vehicle turned too wide, crossed into the oncoming lane, and collided head-on with another vehicle. Both vehicles were totaled and the airbags deployed. Tesla's own Vehicle Data Report for this crash confirms the FSD system (state: ACTIVE_FSD) was engaged and steering the vehicle in the seconds before impact at approximately 20-26 mph, and that FSD disengaged less than one second before the collision. I was lightly pressing the accelerator (Tesla's documented method to confirm proceeding through an intersection) while FSD controlled steering. No automatic emergency braking prevented the vehicle from entering the oncoming lane during the FSD-executed turn. I sustained injuries requiring six months of psychological treatment. I believe FSD's intersection turning behavior is defective: the system executed a turning maneuver that placed the vehicle into oncoming traffic, causing a head-on collision.
