I disagree with your implied belief that cars should have priority on the roads & that in every collision with a pedestrian it's implicitly the pedestrian who is at fault unless it can be proven otherwise.

We all owe each other a duty of care. Excuses about 'she just walked out in front of me' are just that: excuses. The driver in this case had plenty of time to slow down and avoid a collision & simply chose not to do so. That's inexcusable.

The fact that the driver was a pile of self-driving code doesn't change that one iota.
