I do think 5-10 minutes by car is really bad benchmark, but I think a lot of people do feel like that's tenable.

I've lived most of my life in places that are 5-10 minutes by car from a store, and it makes for a very isolated social experience, but also it means that if I don't have a car, getting groceries is a planned 1.5 hour experience.

Now that I'm living within walking distance, I buy a majority of my food multiple times per week, only for a few days at a time, which means I can also go to the coffee shop and see people doing the same thing, have a talk with them, socialize etc..
