Derrick was driving his Tesla Model 3, with autopilot engaged, when the vehicle failed to recognize, and stop/avoid a stationary emergency vehicle in the left lane, striking the vehicle and killing his wife (the passenger) and severely injuring him.

Note: in 2023 a jury decided to not find Tesla Autopilot responsible in the crash.
