Always amazing to me that people think the suburban, drive everywhere, fly everywhere style of America just naturally developed. Every city used to have extensive rail networks. GM and big oil literally bought up the street cars and passenger rail. Then sold it all as the American dream to commute 40 minutes both ways, litterally skipping over not yet developed land in cities that could have offered the same lifestyle. Throw in the boogieman and you got white flight. We don't even stop to think, wow, we drive a long way and a lot and spend a lot on it. Think about it. People spread out before the amenities of life did.
