Small towns in the US already work similarly to European towns, though a bit more straightforward (pun intended).
The town itself is pretty self-sufficient, usually has a co-op, general store, single main road going through downtown, sidewalks, etc.
Larger cities do have suburbs like you're describing, but generally they do have their own amenities like fast food courts / grocery stores / school systems near the entrances of the housing developments, the commuting is generally only because of work, which hopefully we can make more remote to ease traffic for physical workers.
