When i was 13 i rode my cousin's honda three-wheeler and tried to go up a steep hill, gave it gas, and, well...you know what happened, those jokers are so light in the front, forget going up a hill and giving it any gas. Can you say 'roll'?
I like going fast, really fast, as you can tell from the pics of my website posted above, you simply can't go as fast with a 3-wheeler and turn a corner without one day seeing your maker.
I've had my ATV on two wheels often going around sharp turns and leaning to the inside and such. Heck, if I drove a 3-wheeler now with the habits I have acquired, i wouldn't last 5 miles.
