I have one, and they're great fun and good transport, but some of the people on them are insane. On top of that I watch all these really young kids driving these things and they're supposed to be at least 14 years old and they're supposed to have some kind of moped license or something. Not sure what exactly. There's tons of kids on escooters and bikes that look like they're 10 years old and they're driving bikes without any kind of speed governors on them. I think the majority of the accidents involving these things come from underage kids being crazy. Most of the adults I see driving them are pretty civilized. Of course there's always some yahoos.
