It's not a question of blame. The pedestrian put herself in the way of danger, true : but it's considered poor form to blame the victim when the perp. doesn't act in a reasonable manner.
The issue here is not 'who is to blame', but 'why didn't the car respond sensibly to a fairly ordinary hazard'.
If we decide that pedestrians - however badly they behave - are fair game for inadequate driving skills, then we won't need any driving AI. A simple slot-following algorithm like a self-driving train has will do, because there will be no unexpected situations to deal with.
