How do self-driving cars change this equation?
I imagine they'll drastically reduce parking needs, opening space for traffic lanes (reduce congestion) and commercial/services areas (make things closer to home).

I'm not even sure it is possible to satisfy this demand in a city. Houston has 26-lane highways and they are still building more roads to handle traffic. LA uses 14% of all land for car parking and is still building more parking spots. I suppose there must be a theoretical upper bound past which building more space for cars does not eventually induce more driving, but I know of no city that has reached that limit.
