I think you do. I dislike the scooters for my own reasons, mainly the fact that people ride them on sidewalks. But this is not littering.

You tell me if you see a scooter on the sidewalk if that strikes you as the same as people disposing of trash on the sidewalk: loose papers, cigarette butts, plastic bags, etc.

I get what you're saying for the sake of argument, but littering is a disgusting act that makes most people feel like their city is unclean.

Actually they reduce pollution as they are greener than the modes of transport they replace (ICE cars).

I wouldn’t worry too much about that. Here in London, most of the time when I see someone using an Ofo bike it’s some kids who clearly aren’t paying for them, but have found a way to unlock them.
