This is _exactly_ the use case I think self-driving cars are perfect for: a shared fleet of cars continuously picking up and dropping off passengers within cities – eliminating the need for parking and allowing cities to reclaim that ROW for other uses (bigger sidewalks, bikeways, parklets/seating, or even dedicated bus lanes and light rail for high capacity routes, maybe even housing in some spots), finally allowing vehicles to become a crucial supplement to higher capacity public transportation rather than a competitor to it, and hopefully decrease the amount of space dedicated to cars (think highways and sprawl in addition to parking) within cities.
I hope they can pull this off.
