What would it matter with a self-driving car if the commute is four hours? No-one will care. Notice how it's often "worth it" even now to drive for half an hour or so to get cheaper fuel. Except, with no rent in the picture, it will be far more worth it. Add to that that Americans aren't willing to give up bigger cars ("easy-ish" to live in) and ... Self-driving will just become a way to use more public resources for specific people. I just pity the people who still expect to normally get through traffic.
