Super fast Go-Kart racing (http://www.dpccars.com/motorcycle-09/05-01-09page-Super-fast-Go-Kart-racing.htm) I was thinking when will they crash.

You know if we all were forced to use these as commuter vehicles we'd have enough room on our highways and rush hour wouldn't be so bad. Parking wouldn't be as much of an issue... then without the clogged rush hour we can all get home to our big gas guzzling machines and go shopping and do all that other stuff we do.
