What you describe would be a temporary problem - tolls for entering the city would appear out of necessity (see London for a present day example). Life would go on as before except for a bunch of now outraged self driving car owners, mass transit would still be terrible (this is the US after all), and the bickering over parking minimums, zoning, gentrification, etc would continue unaffected with no end in sight (the same as at present). Or perhaps we'd finally get our act together and build out functional mass transit, but I'm not getting my hopes up.
