More convenience stores will be needed. Ones with longer hours.
When I grew up, many years ago, in the East Village in NYC, you had specialty stores. Bread shop, milk and butter and eggs shop, butcher shop, fish shop, fruit and vegetable stand, pharmacy. All separate establishments.
Unfortunately that concept has gone by the wayside. But there was so much more variety than found in modern convenience stores. This was a lower-middle-class neighborhood, nothing fancy. And forget 20 minutes, everything was a less than 10 minute walk.
Now I live in suburbia and the closest stores are about 2 miles away. So of course everybody drives.
