Who is doing the "let live" when a bunch of rental bicycles or a bunch of rental scooters are getting thrown across sidewalks or into a community pond, exactly?

Who is doing the "let live" when a bunch of rental bicycles or a bunch of rental scooters are getting thrown across sidewalks or into a community pond, exactly? In your world, it's incumbent upon me to let them shit up my town, but not incument upon them--either the users or the companies that supply them--to not shit up our town. That's a pretty nasty world.
