While I'm sure that massive changes will sweep through the auto industry over the coming decade, the idea that ownership will disappear seems to ignore fundamental human motivation. For a lot of people (and especially for US citizens) their vehicle is closely tied to their self-image. Furthermore, the idea that people will share their vehicles in order to reduce TCO ignores entirely the fact that when you own something you generally take care of it but when you don't own something you trash it. I'd not be tremendously keen on seeing my vehicle drive itself off to be used by someone else for a couple of hours only to return full of candy wrappers, discarded paper cups, and who knows what other stains and tears. There's a reason electric bike schemes have failed wherever they've been tried. People don't value what they can simply pick up and put down, so they trash stuff. A lot.
