From a public health perspective, it's compelling. The difference between living in, say, NYC and the suburbs of Pennsylvania force lifestyle changes and the culture around travel is very different. When I lived in NYC, I could've stopped exercising all together just from the amount of walking both just to commute and the amount that was expected of me (for instance, everyone walked everywhere, so if you're out with friends and going to a bar 10 blocks away, everyone walks instead of getting into a car). When I lived in the suburbs of Pennsylvania and would walk, there were often long stretches where there was no sidewalk, and I had strangers pull over frequently and ask if I needed help because it was so strange to see a person... walking. Of course it's up to individual people to get the exercise that isn't built into their lives based on their environment, but from a public health perspective, that... isn't working. And I think it's a big contributing factor in why America is so fat compared to other countries; it's so, so big, and so little of it is planned and designed to promote movement and exercise.
