I looked up the point you are making. The data backs you up, 3 wheelers suffer from inherent instability on turns. http://www.youtube.com/watch?v=QQh56geU0X8 "When the single wheel is in the front , the vehicle is inherently unstable in a braking turn, as the combined tipping forces at the center of gravity from turning and braking can rapidly extend beyond the triangle formed by the contact patches of the wheels. This type, if not tipped, also has a greater tendency to spin out ("swap ends") when handled roughly." What a pity. I was quite excited about the prospects.

There is probably a reason that this vehicle has the single wheel in the back. While I think in principle this results in similar instability in accelerating turns as the one-in-front configuration has in braking turns, this is greatly mitigated by the fact that wheeled vehicles generally brake much more quickly than they accelerate.

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.
