It's interesting that we're on the cusp of a major change in our world and no one is really talking about it. Self driving cars will have a profound impact on society. Everything from real estate to logistics will be impacted.
Looking forward to when they get rid of traffic lights and the networked cars just whiz through and avoid hitting each other. They'll also seamlessly zip lanes together on the highway, and traffic waves will be a thing of the past. Maybe China will do it first.
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.
More likely that Waymo's will make it a paradise for pedestrians. It should be possible to cross any road at any point without so much as looking either way.
