ATV’s are fun, utilitarian -— and can be dangerous. (Do we want the nanny gov’t to ban everything that can be dangerous? NO!!!!)
I bought a 3-wheeler 30 years ago, and still have it. Because the design was inherently unstable, they are no longer made or sold, and it’s illegal to ride them, except on private property.
Mine has a small, 125cc motor which was adequate for hauling around an adult, even one of considerable girth and weight. It also has a low, high-torque gear range that makes it capable of flipping over backwards under certain conditions. Not long after I bought mine, they started making them with much larger, more powerful motors, and they could go a lot faster - a recipe for disaster for young and/or inexperienced riders. Add a little alcohol to the mix, and watch out!
In my opinion, the risk of accident increases in direct proportion to the inexperience, stupidity and carelelessness of the rider. Like SUVs, the machines, themselves, don’t maim or kill.
But they have no roll bar, and that’s a potential disaster.
Because, unless you’re driving slow on flat pavement all the time, you have 2 choices when they inevitably flip - stay attached to it and get crushed, or get launched airborne.
Yeah, what fun.
