The closest grocery store is literally in the same building I currently live in. It takes me ~30 seconds from my apartment door to grocery store door.. This (<3 mins to the nearest grocery store) is the norm in a lot of places.
When I lived in my own house in the woods (literally no neighbors), I could bike ~10 minutes to the nearest small farmer's shop, or ~20 minutes and get to a bigger grocery store. The fact that you must drive to buy groceries is, frankly, insane.
