A Tesla Model X owner tells CNN Money that his car crashed while in Autopilot mode over the weekend in Montana. The owner, who identified himself only by his last name, Pang, says he wants to talk to Tesla to determine whether the accident was the car's fault or his fault. His car swerved off a narrow, winding, two-lane Montana highway around 12:30am Saturday while Pang did not have his hands on the wheel. It's the third crash reported to have involved Teslas that were in the semi-autonomous Autopilot mode at the time. Federal safety agencies are investigating one of the crashes, which was fatal.
Pang says he did not receive any warnings from the car prior to the crash, but in a statement, Tesla says, "As road conditions became increasingly uncertain, the vehicle again alerted the driver to put his hands on the wheel. He did not do so and shortly thereafter the vehicle collided with a post on the edge of the roadway." Pang received a careless driving citation after the crash. (Read more self-driving car stories.)
