The “circling the block” is something that Uber etc. already exacerbate.

I think one solution would be to charge for each minute you are in a congested area to avoid having a whole bunch of empty cars clogging the streets.

There's a big limit on how bad it can be with Uber though because each Uber is currently driven by an actual person. That person costs money and places a natural limit on how many unutilized Ubers there will be.

With AVs, this limit no longer exists, and people will start using AVs for runs that currently are prohibitively expensive with care that require drivers.
