Two obvious things from the footages: the pedestrian is invisible until the last moment, and the "driver" is focused on something else, probably a smartphone.

Given of how little time there was between the hitted woman became visible and the impact, a driver action may not have been able to avoid it, but what will be interesting is how his responsability will be engaged or not.

Anyway one advantage of automous car is the theoretical the ability to have faster than human reaction and extra-human sensors. It should have been able to catch the problem.
