Another issue is the enclave-style construction of American neighborhoods. I live in the very very front of mine, with a bunch of commercial businesses just outside that are ~100-150ft away as the crow flies. Unlike the crow, I can't trespass and hop a fence, so to get to these businesses that are "right there", I'd have to walk 0.7 miles, almost all of it with no sidewalks, and more than half on busy 4+ lane roads.
