I mean mass transit isn't an issue because we don't really have it. There's a few million people living here and although we have a bus system, no one I know uses it. When I mentioned trying to get from my densely housed, grid street area to the airport with mass transit people considered that about the most bizarre thing they'd ever heard. (Google says about two hours on mass transit for the 15 minute drive.)
Yet I'm sure you realize that in other parts of the world that could not be the case.
There was an article on HN a few months ago about this difference between USA and Europe. In USA having a car is almost mandatory, because of the distance between the cities and the state of public transport. In Europe not having a car is not not so uncommon (almost everyone of my friends and I don't have a car), especially if you live in a city.
