You could still have pedestrian crossings with buttons etc which signal the cars to stop, just the same logic as we have now. Maybe even physical lights for redundancy. Pedestrians are pretty rare in most places though so this shouldn't slow things down too much.
Walk? Waymo already stops at crosswalks (marked or unmarked) if a pedestrian looks like they are crossing or starting to cross. That is more than I can say for human drivers. I’m confused why you don’t think this is just a win for pedestrians given how messed up things are now.
