For example my parents live in a mini-subdivision of a dozen or so houses about 5 miles outside the nearest city limits. The walmart is on the way out of the other side of town.
Poor city planning that makes cars all but essential is the problem, not the dozen houses way out in the sticks. In Germany even towns with a population of like 30k have at least basic necessities within cycling distance, and Germany is way worse than, say, the Netherlands. I'm pretty sure that the majority of the population lives in towns that are larger than that.
