I've described conditions under which the streets of Chicago are packed full of pedestrians during rush hour in January. If they haven't moved south because of the weather, they're not going to move south because of some damn scooter.
No one can predict the ultimate uses of a new technology. Around here there are closed communities that only allow golf carts on the streets. I think that sucks, but they bought it and that's what they want.
My guess is that the younger siblings of the brats that drive BMWs to high school will be the first big market for Segways.
After that, who knows.
