HikerChick, I have been around ATV's since they 1st came out. There have been many deaths and injuries with the 3 wheelers. Quads have their fair share, but no where as many. The bike companys have quit making 3 wheelers and alot of states have outlawed them. You information may have come from street trykes. From personal experiance, there is no similarity between street and ATV. the 3 wheeled Atv is hard to hold straight. I shudder to think of having to steer one at highway speed. The quads actually fun to steer, some even have power steering.
