They don't seem to be an issue in Chicago at least from my perspective. It wasn't a free for all though, they had two pilot programs and they are banned from the downtown/Loop area which is the highest density area of the city. Scooters must be attached to a fixed object like a light pole/street sign/etc. Also it helps that Divvy (Lyft) retrofitted their bicycle docks to allow scooter docking as well.
