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.
