If you live within 1 mile of a grocery store you could easily walk, and you don’t need anything else on a regular basis. Use a bicycle and 5 miles becomes just as easy. People lived thousands of years without cars. The problem is our cities are built around cars, and they’re built poorly because of it.
If I lived about a mile I could shop daily. That’s an effortless walk. On the occasion I buy heavy liquids, backpack or bicycle.
