> Right, and that acts as a hard cap. You can't travel to two places at a time, and you aren't going to want to spend every second of your life traveling somewhere. So, unless you think Winnebago's are going to be a thing everyone lives and works out of 24/7/365, there's a very explicit hard cap on transportation usage.

This is why autonomous vehicles are concerning. It's going to become possible to consume a lot more transportation without using your own time. (Think: empty vehicles driving around rather than being parked, or empty autonomous taxis just driving around.)
