Like BMW, Honda also feels that motorcycles of the future will be self-balancing. Here's a demonstration of their Riding Assist technology, which does a Segway one better:
This is no gimmick, by the way; self-balancing motorcycles would be a boon to riders at low speeds and at the beginnings and ends of trips. If you've ever seen the awkward moves a biker has to do to maneuver out of a crowded parking lot, or seen one trying to walk and push several hundred pounds around an obstacle, having a bike that can follow you makes excellent sense!
I do wonder, though, how people might abuse the technology once it's released. I think it's just a matter of time before someone tries using their bike to help them move a sofa.
