Tesla driver says car was in autopilot when it crashed at 60mph

Driver of Model S, which failed to stop at a red light and collided with a firetruck in Utah, told investigators she was using the semi-autonomous system

The driver of a Tesla car that failed to stop at a red light and collided with a firetruck told investigators that the vehicle was operating on "autopilot" mode when it crashed, police said.

A Tesla Model S was traveling at 60mph when it collided with the emergency vehicle in South Jordan, Utah, on Friday, causing minor injuries to both drivers, officials said Monday. The Tesla driver's claim that the car was using the autopilot technology has raised fresh questions about the electric car company's semi-autonomous system, which is supposed to assist drivers in navigating the road.
