Maybe cars sit idle 90-95% of the time, but isn't it the same 90-95% of the time? I would imagine the peak utilization is much higher. Furthermore, if self-driving cars become a reality, then I imagine utilization would dramatically increase. Now that I can just send my car to pick up the grocery, I'm much more likely to send it on random errands.

I expect local governments to enact per mile taxes, replacing gas taxes, which at some point makes this unaffordable to constantly have your vehicle on the move for you (but still affordable if its part of a rideshare fleet generating revenue).
