I think the mindset is probably closer to "tens of thousands of people each year are needlessly dying a preventable death, and many times more people are injured" With that ideology, you are already ready to give up control of the vehicle. It's not much of a jump from there to give up ownership, especially if that means only paying for what you use and not having to constantly maintain it.
