A futuristic hovering mail delivery assistant vehicle, and it still takes a key. A key.

Looks like it would have ballance issues... and yeah like Lalaca pointed out, a fricken key! Shouldn't it be activated by finger prints or some weird ass combo using her tounge?

No, it's a self-balancing unicycle.

Odd idea, the one in the wiki looks weird. I rather use the one drawn here. Though it still looks like it would be hard to balance. Well since it's a real item of today no need for fingerprints or tounge kiss combos to start the thingy up.

I kinda want one now >.>
