Honda has been demoing its sitting Segways for years now, but the Hammacher Schlemmer version has one crucial advantage over them: it's actually for sale. So instead of just being tantalized by a future where legs are an unnecessary human feature, we're now officially living it.

Comfort and safety are the top features when it comes to buying a new car, so in an attempt to make its U3-X personal mobility device more consumer-friendly, Honda has improved both those aspects in its new Uni-Cub concept.

The next time you ride NYC subway, you might notice an officer mounting one of four brand new T3 scooters. But the NYPD aren't nearly the first cops to show off their sweet three-wheelers. Thank goodness.

Riding Honda's U3-X personal mobility prototype is easy. Very easy. Gut-fatteningly, motivation-drainingly, muscle-atrophyingly easy.

I thought the Honda U3-X was weird, but this personal mobility device prototype by Nissan and AIST actually separates into a whacked out pair of motorized skis on stilts. With its unstable seeming controls, I think I'll stick to walking.

Jalopnik just posted this crazy Honda unicycle, the U3-X, with "omni traction drive." It's definitely the first personal mobility device that might help you fulfill your lifelong dream of re-enacting Jamiroquai's "Virtual Insanity" video. Pics and details at [Jalopnik]
