I think you're dismissing people's issues too easily. I've lived in Alabama before, and heeellll no I wouldn't want to settle down there. This isn't the only problem I had with the area (I lived in several different parts), but it felt super, super hostile to not-driving. And I should know, I had to bike around a lot as a mormon missionary there. We didn't even bother checking transit, it was taken as a given that it would be too slow and sparse to be useful.

My wife is even harder on this line than I am. We live in Munich now, and the biggest reason she doesn't want to come back to the US is that she doesn't want to go back to driving everywhere, and there are only a few cities where a family can reasonably and easily get away without a car.
