Police in California say they were able to stop a Tesla vehicle that was speeding with the driver sleeping inside. The California Highway Patrol (CHP) reported the Tesla’s Autopilot driver assistance system might have made it possible for officers to stop the vehicle. The incident was described in a police report. It happened early in the morning on November 30. The report said the CHP officers observed the Tesla Model S traveling at speeds up to 113 kilometers an hour on a road near San Francisco. The car was violating the speed limit for vehicles in the area. When officers drove up next to the vehicle and looked inside, they saw that the driver appeared to be asleep in the driver’s seat. The report said the officers then drove behind the Tesla and turned on their car’s warning lights and siren in an attempt to get the driver to stop.
