How long has this stuff been around? It would seem like it's just not the type of thing that anyone can use legally and walk around in public without possibly walking into traffic, or even getting behind a wheel from what I've seen in the vids and read on here. So I'm curious about it's background.

Oh, and thank the lord above that someone is able to come onto this site and make a 1st post in such an educated way. HaredX... thanks!
