I was thinking the infrastructure and amenities state of US suburbs, where they're basically stamped down in blocks off a highway. I live in a single family home and drive a car in the UK, but there are tons of amenities within walking distance (and I can walk anywhere), community events and green spaces, etc. I can drive, get a bus or cycle into the nearest city, which my town is clustered near to, so opportunities are aplenty. I know my neighbours, family are nearby, and so on. The vibe I get from American suburbs is that they're much more like isolated house-units and if you want to do anything you have to drive to somewhere totally different.
