A Tesla driver killed in a California crash had posted videos of himself driving without his hands on the wheel — with investigators probing whether the car’s Autopilot mode was “a contributing factor.” Steven Michael Hendrickson, a 35-year-old father of two, died around 2:30 a.m. on May 5 when his white Tesla Model 3 struck an overturned semi on a freeway in Fontana, about 50 miles east of Los Angeles. Another man was seriously injured when the electric vehicle hit him as he was helping the semi’s driver out of the wreck. The California Highway Patrol (CHP) initially said Thursday that the car’s Autopilot “was engaged” prior to the crash, but later walked it back to say there “has not been a final determination made.” But Hendrickson regularly posted about his love for his car on his social media — including several posts bragging about the car driving unaided. One video on his Instagram account showed him riding in the driver’s seat without his hands on the wheel or foot on the pedal as the Tesla navigated freeway traffic. “Best carpool buddy possible even takes the boring traffic for me,” he wrote alongside the clip.
