Hi!
I think the person responsible for this accident is the safety driver. Even if the car was in autonomous mode, she should still have been paying attention to the road instead of watching "The Voice". Because of her lack of vigilance, she did not see the pedestrian in time and it was too late when she braked. So, even though the car should have recognized the pedestrian and braked, it is the safety driver who is truly guilty, as she should have known that autonomous cars are not yet fully reliable.
