 You can get on, you can rent one, and you've never ridden a scooter before, and you zip down the sidewalk, and, yeah, you're presenting quite a danger both to yourself and to those around you. Well, and in theory, the bike riders have to at least give hand signals when they're turning, but on a car, you've got to have working turn signals, a working horn, all these other things. On the scooter, none of that is present.
