I think this fundamentally misunderstands what people want...

Currently I live in a city with an OK pt network; in the a high density apartment. I chose this because I can catch a train to work, go drinking locally, and I dislike driving.

If I could rely on a driverless car, i would happily live further out in the suburbs, as the driverless car removes the upsides of density more than anything else... And I think this is a common sentiment, driven mostly by housing costs.

And then you have the cost of a trip, of owning vs rideshare... If its my car I can choose the furnishing, pay for fuel or power however is most efficient for me (eg solar), not have to pay for cleaning, and store my stuff in the car.
