If urban grocery stores weren't required to have 100 parking spaces, there would likely be more neighborhood shops and you wouldn't have to take the subway to get to the grocery store. In thriving, dense urban environments without excessive parking, it is at most 3 blocks to the grocery store, often less.

Edit: Quoting from the article: "These retail corridors have narrow parcels on which building a store and providing the required parking is difficult. As a result, much commercial land remains vacant, and adjacent neighborhoods lack retail services, even food stores".
