Two Texas men are dead after a Tesla Model S crashed late Saturday, apparently while in autopilot mode. "No one was driving" when the car hit a tree in Spring around 11:25pm, Harris County Precinct 4 Constable Mark Herman tells Click2Houston. The brother-in-law of one man says the owner of the car decided to take his best friend out for a ride, and may have gotten into the backseat after backing out of the driveway. The car crashed just a few hundred yards later, after failing to negotiate the curve of a cul-de-sac, going off the road, and slamming into a tree. It was traveling at a high rate of speed at the time, KHOU reports.
The vehicle burst into flames after crashing, and the brother-in-law says family members watched for four hours as authorities were unable to put out the blaze because the fully-electric car's batteries kept reigniting. Ultimately, 32,000 gallons of water were used and deputies got in touch with Tesla for help. Only after the fire was extinguished were the bodies recovered, one in the front passenger seat and one in the back. No one else was in the car. Autopsies will be performed. Investigators "are 100% certain that no one was in the driver seat driving that vehicle at the time of impact," Herman says. "They are positive." The men were 59 and 69 years old.
