Car Vs Bike...is it fair, why does it happen?

Automobile:

You drive down Interstate 95 doing the speed limit, minding your own business and trying to get to your destination safely. You understand the laws, and you, like many enjoy the security provided to you by the designers of your car. As you ponder the benefits of this safety, you are passed at high speed by a series of brightly colored noisy motorcycles doing in excess of 175mph. The tail rider notices your panic and slows down to your speed, then pops a wheelie, accelerating again to catch up with his friends. Un-nerved, you decide to take the scenic way home, getting off of the highway. As you are driving the country roads, you start to hear a load racket coming from behind you. It isn’t until you get to a stop sign that you realize that the racket is a series of strait pipe, non-helmet wearing cruiser riders that are making all the noise. When you move from the stop sign and get beyond the intersection, the group behind you decides to pass. They roar by, deafening you as they pass. Now just aggravated, you finally get home and to relieve the stress from the ride home, decide to take a walk in the woods. You begin to unwind, listening to the birds, smelling the forest, and enjoying nature. Then, off in the distance, you hear the sound of an engine: Chainsaw? Mower? How odd. What is even more odd if that it seems to be getting closer, then, all of a sudden, out of the woods, comes a group of smoking, loud, dirt bikes. As they pass they kick up the mud on the trail and you get covered. That was the last straw. The next day you do not signal on the highway, or yield to the fast sport bikes, as a result they lose control and crash. You do not allow the cruisers to pass instead blocking their way. When they do pass they almost hit an oncoming car. You set spikes in the trails to blow the dirt bike tires. You have become a vigilante against bikers. You are not alone though. There are many people just like you who wage war against them, in California oil is poured on curves, sharp rocks are thrown, and neck-trip wires are strung on trails. Others, merely, enact legislation to restrict bikes. To an automobilist, the National Transportation Safety Board, and other traffic councils, motorcyclists are a scourge and a danger on public ways. Are they really or is it a few who ruin it for the rest?
