I've been wondering what happens when some elderly rider has a stroke and falls forward while riding on the thing. Months later a decomposing body or skeleton is found riding down a lonely sidwalk?
That's pretty funny, in a distasteful way.
Yeah, it wouldn't fall over... until the batteries ran down. And how would you catch it? Someone would have to jump from one to another.
I can see it now: "Speed IV - A Segway to a better movie"
