Autopilot could not have been engaged in fatal Tesla crash – TechCrunch

Tesla’s advanced driver assistance system,, Autopilot,, could not have been engaged on the stretch of road where a Model S crashed last month in Texas, killing the two occupants, according to a preliminary report released Monday by the National Transportation Safety Board. The results help clear up some of the mysteries around the crash, which has received widespread attention after police reported that no one was in the driver’s seat.

It led to speculation that Autopilot was functioning at the time. According to the NTSB, only adaptive cruise control, one of the functions in Autopilot, could be engaged in that section of the road. The report says that Autosteer, another feature that keeps the vehicle in the lane, was unavailable on that part of the road. The preliminary report supports comments made by Tesla’s vice president of vehicle engineering Lars Moravy, who said during an earnings call that adaptive cruise control was engaged and accelerated to 30 miles per hour before the car crashed.


NTSB also confirmed there were only two occupants in the vehicle. When the two men were found, one was in the passenger seat, and the other was in the back seat. This led to speculation about whether Autopilot was engaged and even conspiracy theories that there was a third occupant.

“Footage from the owner’s home security camera shows the owner entering the car’s driver’s seat and the passenger entering the front passenger seat,” the report reads. “The car leaves and travels about 550 feet before departing the road on a curve, driving over the curb, and hitting a drainage culvert, a raised manhole, and a tree.”

The NTSB said it would continue to collect data to analyze the crash dynamics, postmortem toxicology test results, seat belt use, occupant egress, and electric vehicle fires. All aspects of the crash remain under investigation, the NTSB said.

The NTSB’s preliminary report also indicated that the crash of the Tesla Model S, which caught fire after hitting a tree, destroyed an onboard storage device and damaged the restraint control module — two components that could have provided important information about the cause of the incident. The agency said the car’s restraint control module, which can record data associated with vehicle speed, belt status, acceleration, and airbag deployment, was recovered but sustained fire damage. The NTSB has taken the restraint control module to its recorder laboratory for evaluation.

The NTSB is investigating the crash with support from Tesla and the National Highway Traffic Safety Administration. Harris County Texas Precinct 4 Constable’s Office is conducting a separate, parallel investigation.
