Ok, so if a scooter is left on the street where it’s not supposed to be, fling it out of the way. The last person using it will either get billed for damage, or the company will see their business model become unworkable.
Bingo! We have a winner!
Back when the scooter craze started, I remember seeing an article that had companies having to fish scooters out of a lake where they were deposited, presumably by an annoyed person (or persons).
