Tesla Inc’s autopilot system was unlikely to have been a factor in a Florida car crash this week which killed two teenagers, the electric carmaker said in a statement issued late on Wednesday. The autopilot, a form of advanced cruise control that has come under scrutiny after two crashes this year, was not engaged when the Model S car drove off the road and hit a concrete wall, catching fire, the company said, although it added that it had not yet seen logs from the crash.
