It is the technology of the future: cars with self-driving capabilities.
But now that technology is under investigation after a deadly crash involving a self-driving Tesla vehicle in Florida.
FOX 10's Troy Hayden has more details.
It is believed to be the first death involving a car in self-driving mode in the United States. Investigators are now looking into 25,000 Tesla cars with the technology. Meanwhile friends of the man who was kill in the crash say he had a need for speed.
The 2015 Tesla Model-S uses camera, radars and sensors to drive on highways and change lanes and speed. But now the cars are under investigation by the National Highway Traffic Safety Administration.
On May 7, 40-year-old Joshua Brown and the auto-pilot feature on his Model-S failed to see the white side of a tractor trailer against the bright sky in Williston, Florida.
Tesla says the trailer was high enough for the car to go under it. If the car had hit the front or rear of the trailer, the crash safety system may have prevented serious injury.
Brown's friends say he loved showing off his Tesla and said it was the best car he ever owned. But they also say he had a history of speeding.
The truck driver from the deadly crash says Brown was driving fast at the time.
Records obtained by the Associated Press show Brown had eight speeding tickets over a six-year span. The most recent ticket was in 2015 for going 64 in a 35 miles per hour zone.
The truck driver from the crash also told the Associated Press that Brown was watching a movie when the crash happened.
Florida Highway Patrol did not confirm that.
