DETROIT (AP) — A Tesla driver is saying: don't blame the car — now. Authorities in Minnesota say driver David Clark first did blame the Autopilot system for a crash he had Saturday evening.

They say he told sheriff's deputies that when he engaged the Autopilot feature, the car suddenly accelerated, left the roadway and flipped over in a marsh. But that isn't the story he's telling now.

In an email sent yesterday to the sheriff's office, Clark says he had it wrong. He says after discussing the crash with fellow passengers, he now believes he disengaged the Autopilot by applying the accelerator before the crash.

Clark and his passengers sustained minor injuries.

For its part, Tesla says it's investigating the incident — and will cooperate with local authorities.
