As I said in another post, most of these things are not new. They've been done. Maybe not "on a computer" or "with an app", but they've been done, and are the reason why the regulations were enacted. The startup that tried to sell parking spaces was one such example. There were regulations on the books making it illegal to sell a public parking space for a long, long time. Why? Because someone tried to do it before, and it was decided that it should not be allowed.
