LAKE STEVENS, Wash. (AP) — Law enforcement officials say a Tesla in autopilot mode crashed into a Snohomish County deputy’s patrol car north of Seattle, causing significant damage, but no injuries.

A deputy responded Saturday to a report of a motorist in Lake Stevens that had hit a power pole. Sheriff’s officials say the deputy parked on the shoulder of the road with the emergency lights flashing and exited the vehicle to speak with the fire units on scene.

About 30 seconds later, a Tesla in autopilot mode struck the deputy’s vehicle, heavily damaging the front driver’s side, including sheering off a front tire.
