My point is that you aren't simply pushing robots off the sidewalk and getting a better city. You have externalized the problem somewhere else. "Look, our streets are free of garbage", he says, dumping it all into the ocean...
But isn't this whole concept externalizing the commercial micro-transit problem onto pedestrian-only right of way? The sidewalk is the ocean in this metaphor.
It’s not clear to me there even is a “problem”. We did just fine before there were either robots or DoorDash drivers clogging up the road/sidewalk. (Admittedly DoorDash was very handy in 2020.) The problem is in allowing commercial interests to unilaterally clog public infrastructure.
