Cost is only one dimension of renting a car. As long as the car rental companies keep making it as painful as possible, it won't be a solution for usual usage. Hopefully Waymo goes after them too.
Very much. They often don't have cars at all - despite letting you reserve them. Or they are not open when your train arrives / leaves. I'm considering a 3 day drive my next trip in part because it is the only way to be sure we can get around when there.
(we are going to a remote location where I wouldn't expect public transit to serve, but the train station is in a small town that still should have some transit but doesn't)
