Early in July there was an accident involving a Tesla Model X SUV, and the driver is blaming Autopilot for the wreck. The rollover crash occurred on the Pennsylvania Turnpike about a hundred miles east of Pittsburgh, with the vehicle striking a guard rail followed by the concrete median before turning fully over and ending up in the middle lane.

A rollover accident with a Tesla is a rare event — the low center of gravity thanks to the heavy battery floor makes the Model X and its Model S stablemate exceptionally difficult to flip — and placing the blame on Autopilot makes the accident an even rarer occurrence. The wreck comes just a few days after news of a fatal Autopilot wreck involving a Model S that's been blamed on to driver inattentiveness.

Tesla has been adamant from the start that Autopilot is a beta that requires attentiveness from the driver, and consistent with that statement of driver responsibility the police investigator assessing the circumstances of the wreck has indicated that he'll like cite the owner of the vehicle for the accident.

Taking it one step further, Tesla has stated that they have no data that indicates the Autopilot system was engaged during the accident, let alone at fault. Tesla vehicles transmit information back to the company on a periodic basis, including diagnostics, crash data, and Autopilot logging information.

The company said in a statement that they "received an automated alert from this vehicle on July 1 indicating airbag deployment" from the vehicle in question, but logs that would indicate if Autopilot was engaged were never transmitted. "This is consistent with damage of the severity reported in the press, which can cause the antenna to fail," Tesla said, but their multiple attempts to contact the owner in the days after the accident were unsuccessful. But given the data that Tesla had received prior to the wreck, they say that they "have no reason to believe that Autopilot had anything to do with this accident."
