> Or worse, people and companies will relocate to cities with exclusive self driving car policies

So people will relocate to avoid traffic? Why doesn't this happen today? Suppose San Francisco decided to not enforce self driving laws to protect small businesses and preserve community infrastructure and culture. Now suppose Phoenix (only picked because they've been progressive with self driving technology) does enforce self driving laws, would you expect a mass exodus from San Francisco to Phoenix?

Yes, people do move cities for better quality of life (e.g. their commutes suck). Companies have been known to do similar things.

Right now Phoenix is not even on the map for most of us. If they did something like this (at the right time), then it might be.

Additionally, it isn't really SF vs. Phoenix. Think global competition: if developing mega cities in Asia adopts this before American cities do, they will be able to more quickly catch up with and very likely exceed their American counter parts in a short period of time economically.
