The NTSB is not sure why the automation didn’t try to avoid the crash, looking at possible of faded lane lines and bright sunshine that affected the cameras, as well as closer-than-normal vehicle in the lane in front of the SUV.
The vehicle wasn’t the only thing found at fault. The cushion at the end of the barrier had not been fixed after a crash less than two weeks before.
The big takeaway NTSB issued though that a self-driving mode like Tesla’s Autopilot doesn’t mean that the car can fully be operated while the driver is doing other things.
"You can't read a book, you can't watch a movie or TV show, you can't text and you can't play video games," NTSB Chairman Robert Sumwalt said, the AP reported.
