Not to disagree, but I believe many of the problems with three-wheeled vehicles are solved by putting the single wheel at the BACK. e.g. the Peugeot HyMotion3 http://www.youtube.com/watch?v=_9ZT8adga1E

The main point of HyMotion3 is motorcycle-style whole vehicle body leaning inside the turn - completely different game.
