That's a really good post and I agree that if the only added-demand is for people like me (btw, I am someone who only wants something to get from A to B with present cars) then that cannot possibly outweigh the likely large cost differential for the many many people who find cars difficult to afford. I'm sorry for communicating poorly, but my point was more that it is not likely possible to predict all the consequences of a completely new technology and how behavior and economy will change in response. And I'm not even predicting anything myself about demand (beyond my own desires, which is dicey enough to predict) -- I am just curious where the confidence comes from when people state that ownership will be significantly reduced as an obvious fact when IMO that is certainly plausible but I don't have any reason for such confidence.
