I mean the idea is that good urban planning would enable shorter and more frequent grocery store trips. Rather than a supercenter supplying everyone within 30 miles, requiring long drives, you'd have things distributed by need, i.e. general food stores every couple miles, more specialist places potentially farther away. Our current layout and shopping habits are contingent on car infrastructure and massive federal subsidies.

Would also decrease waste and increase general health, since fresher, less processed food could be purchased.
