That's why in places with good infrastructure, the infrastructure is separated.
Pedestrians are on tall sidewalks with few ingress points for cars (unlike in the US where every corner has a lowered curb for 20m just in case some random truck needs to go on the sidewalk??). Sidewalks are on streets with traffic calming, frequently separated from the actual road by a nice hedge or trees or a patch of grass.
Bike lanes are completely separated from roads and intersections are also traffic calmed (no slip lanes, roundabouts, multiple lanes separated so that the intersection doesn't require crossing 6-8 dangerous lanes at once).
Etc, etc.
Do you think it's realistic to maintain 2 sets of road infra for cars (human vs AI)? We can barely maintain 1 set and it's already forcing many places into deeper and deeper debt or even bankruptcy.
