Right, I just realized I forgot another important effect if we go the autonomous taxi route. Currently we have somewhere around 5 parking spaces for every car. I bet we could at least cut that in half with autonomous cars, making it reasonable to develop more densely, meaning shorter driving distances, and making trains a more attractive option for some trips.

Not in the places with lots of population density.
For example, SF may have more cars than parking spaces. It certainly doesn't have 5x as many.

almost no difference.
For example, I have two parking spaces. One on the street in front of my house and the other in my backyard. The latter isn't going away and the former won't make any difference.
