I think there also needs to be a parcel pickup/dropoff hub. Plus there needs to be an option to either drive through, or to drop the car for a wash - you could have a cafe and small store, then by the time you're finished the car is clean, refuelled and filled with your purchases and deliveries.

I once had a business idea where you could order a package containing one or two squares of special brownie plus a bunch of normal baked goods to sate the munchies after.

I do not partake or break the law. I just think that having an entire pan of special brownies sitting there after eating the first is playing a dangerous game.

A talented baker could make good money with a side hustle like that

And not at inflated prices either, I'd be so all over that!
