Americans love big cars. They buy huge trucks and sport utility vehicles (SUVs) that could go across a desert and back to take their kids to school. It really is a horrible thing for the environment, since these vehicles produce more pollution and use more gas than smaller vehicles. For Americans, however, cars are more than just a way to get somewhere. They're symbols of wealth, and sometimes, the one place they can get away from everything. Driving in their cars by themselves, they don't have to think about their work, family, love-life, or anything else but the open road. They put some good music on the car stereo, turn on the air conditioner, roll up the windows, and just drive.
