I actually saw this in action... It throws a plume of snow 30 feet in the air when it gets up to speed. It also requires you to have several of your biggest beer-drinking buddies in the back seat to give the rear wheels more traction.
So, you're snowed in your house with two feet of snow and need a way out, but are too lazy to shovel. Luckily, you happened to have a welder, some steel, a bicycle, a 3.5HP go-kart, and some wood laying around. So what do you do? You make a plow to get yourself out!
