California Highway Patrol is trying to figure out if that driver had his Tesla's Autopilot engaged while behind the wheel.
The CHP said they spotted the grey Model S driving around 70 mph at 3:37 a.m. Friday. When the CHP pulled up close to the vehicle, they said it looked like the driver, Alexander Samek, was passed out at the wheel.
