San Francisco 49ers head coach Kyle Shanahan is offering a deeper look at the July 11 car crash that left him with multiple injuries. Shanahan previously accepted responsibility after reaching for his phone while driving, but he now says he cannot rule out a possible issue involving his Tesla Model S and its Autopilot system.

Shanahan said the autopilot function apparently went off when he tried to retrieve a fallen cell phone.

He still takes responsibility, saying ‘you don’t just turn it [driving] over to a computer.‘
