I’ve lived in Florida, Kansas, Minnesota, and Indiana and visited over 40 states. Except in a few places my experience is that most people don’t live within walking distance of a car. Well, let me be more precise. Those who do live within walking distance to a grocery store tend to not have a pleasant enough or safe enough route to walk there to do so on a regular basis. Traversing a giant parking lot with a bunch of car drivers unaccustomed to pedestrians is unpleasant.
Yeah my comment only really applies if you can choose the region of the country you live in. I don't really know what it's like in e.g. Indiana, so I trust your judgement on it.
