Self-driving cars will one day pull over for police

Self-driving cars have a lot to learn before they’re ready to tackle every situation, including how to pay attention to police or road crew hand signals.

The Detroit News reported Monday about a California Highway Patrol officer who attempted to stop a Tesla Model S cruising at speeds above the posted limit. Lights and sirens failed to address the speeding, and it wasn’t until the officer pulled alongside the Tesla that he saw the driver had fallen nodded off. Tesla’s Autopilot system had taken over driving duties.
