The SUV, or Sport Utility Vehicle was first made by the army because of their need to navigate various terrains without being in a tank or helicopter. This was fine, and in fact this still is a legitimate use for SUV's.
Around 10 years ago however, carmakers figured out that yuppie scum would love to combine the luxury of oversized sedans with the massive size of a tank. Afterall, it would appeal to their egos in every way. So they created the ugly, oversized, gas guzzling behomoths we today collectively refer to as SUVs. Initially they appealed to off-roaders and back to nature types who didn't want to shell out dough for a work-week car and a weekend getaway truck. That's all fine and good, but look around today and you'll notice that only a small percentage of SUV owners are rugged Renaisance men.
Instead, they're driven by crazed soccer moms, preppy private school teenagers and asshole business executive types. These people don't drive safely to start with, and when you factor in cell phones, under-experience, kids, and over-stressed lifestyles into the mix, the last thing anyone should want is the added factor that these monsters weigh tons more than your everyday Civic or Taurus.
This is where the part about you making a cultural statement comes in. When you see one of these monsters while you're driving around, get your pennies ready and throw them at it. You've just choinked!. Make sure you yell "CHOINK!" so everyone in the vicinity gets the message. It is even better when the owner gets the message, but be warned: Don't hang around and confront them in person. You don't want to have to deal with the kind of person who would drive one of these monsters around. We can only hope that enough people get the message and in 10 years, SUV's will go the way of the dinosaurs that they are.
