ATV's (three wheelers) were created for kids to ride on desert and ranch lands to increase the customer base and demand. ATC's were deemed dangerous because the adults that bought them used them as baby sitters and failed to supervise, advise, provide protective gear and train the kids that they gave them to. The manufacturers did not want to lose their sales revenue and the market was strong for the lazy people who wanted to participate in off road recreation, but did not want to learn how to control a motorcycle, so they add ed a 4th wheel to the ATC and rebranded it an ATV. With 4 wheels, no new skills needed to be learned to operate one, but roads were needed be able to go where where the motorcyclist and other active people went. It's kind of like getting off a horse and into a automobile. The horse only needed a single track to go where it wanted to go. It could negotiate steep hills, cross streams and stop and turn quickly. Cars needed two tracks with relatively no obstructions between the tracks. They needed special tires and compliant suspension to go where the horse rider could go and even then the vehicle was limited by the fuel available, changes in altitude and even the weather. Horses were relatively unaffected by those variables.
ATV's are small cars. They need two tracks with relatively no obstructions between the tracks. They were primarily designed for desert and ranch land operation. Maneuverability is not high on the list. If you want to turn tight and negotiate obstructions, get a motorcycle or a horse. If you want to operate on relatively clear landscape and need the work performance a four wheeled vehicle provides over a motorcycle or horse and you don't have the clearance for a full sized truck, then get an ATV.
While referred to as ALL TERRAIN VEHICLES remember, they are marketed as RECREATIONAL VEHICLES. You don't use a motor home to haul logs out of the timber and neither should you use a RV ATV.
I am well aware of the benefits and shortcomings of both motorcycles and ATV's and own both, but while I may use an off highway motorcycle to make a quick trip to a remote store or restaurant overland as the crow flies, the off highway ATV is not used on public roads to get to the same place. The roads are for vehicles intended for on road use.
Same as tools; screwdrivers are not pry bars, motorcycles are not horses, ATV's are not boats, but that does not stop us from using them for unintended purposes. Just stay aware of the limitations, use them as your ability allows you to and don't complain that it doesn't suit the application. If you need an very agile ATV find one currently manufactured or make your own. Does anyone manufacture an ATV with all wheel steering? Maybe there is your market niche and you could manufacture a vehicle to fill that niche. What would it cost and how much demand is there?
