20mph is hauling it on a bicycle. A normal cruising speed on a bike is more like 12-15mph. So that's more like 3.75mi. But yes, for all the suburbs I've lived

20mph is hauling it on a bicycle. A normal cruising speed on a bike is more like 12-15mph. So that's more like 3.75mi. But yes, for all the suburbs I've lived in I've had the choice of dozens+ of restaurants, a few grocers, various stores, office parks, and more within 5mi. There's definitely places where this isn't true but it's not like all suburbs take two miles to leave the pure houses neighborhood.
