 I'm not even sure what the law says about where these scooters are supposed to be. If they're in the street with all the regular traffic, then the scooter rider is at great risk. And if they're on the sidewalk, they're putting all the pedestrians, especially the older ones or the younger ones, kids, at risk as well. You've got a 200-pound guy on a scooter who clobbers your 10-year-old son or daughter. You can do some real damage. And, of course, with cars, you've got to have liability insurance. I'm not sure how that works with scooters.
