A four wheeled vehicle ridden by bullies who think they have the right to ride wherever they want, trespass, and assault anyone and anything that gets in their way. Used by assholes to destroy private property, private roads, and the environment. Supported by most states because they make money off of registration and of course, the states don't really care about protecting the environment, but they will take your money for "conservation" so they can give more grants to ATV clubs to build more trails.
The wardens refuse to enforce the ATV laws to protect landowners from trespassing ATVs.

Among the most ecologically destructive devices ever invented. They bring ruin to natural areas, destroying thousands of native plant and animal species, tear up cropland (in case you don't remember that's what keeps us from starving to death) and otherwise cause severe amounts of soil erosion (which in turn degrades the water quality and aquatic habitat). For these reasons they are especially attractive to rednecks and other irresponsable people.
Tax dollars are wasted repairing the damage caused by ATVs.
There have been cases of arguments where ATV riders have actually killed farmers & property owners.

"Dude, people with skill stay on two wheels bro. stop wrecking tracks and go away."
