same hatred applies to anybody who rides a Razr scooter on the sidewalk. Besides the annoying part of them zipping around, these people always look like idiots. The population that rides them, based on my observation, is usually women and Indian men. And children, but that's a given.
in my old neighborhood, Fairway put up a sign that was basically "if it's not a stroller but has wheels, we probably don't want it in our store, so don't bring it into our store". The same logic should apply to the NYC sidewalks.
