Looking at the video, if she walked into the road out of nowhere then there's no way anyone could have stopped, robot or not. However I don't know much about how far these cars sensors extend. Do they only "see" the road around them? Because if so then what Kizzy says is right... a human driver may well have been "aware" of her at the side of the road or looking like she might go onto it. Also humans can pick up on erratic behaviour and adjust accordingly... an AI can't possibly know if someone is behaving "weirdly" or unpredictably.

But yeah... also, she does just walk out right in front of it. She can't possibly have looked / must have been distracted. Whether or not the car is electric is relevant too because they're so quiet... and people have grown up hearing cars coming as well as seeing them, so if all is quiet people assume they can walk out without looking properly.
