Cars are everywhere. In big city and small towns, the preferred method of transportation is the automobile. People can get to where they need to go quickly and easy, and it has given a new kind of freedom to many people who may not have experienced it ago. But was driving really the best thing for our society? I argue that it is not. First, pollution was a serious problem, and more cars only make them worse. There is just not way to reduce pollution without decrease the number of cars on the road. Second, cars are very dangerous. Traffic accidents are responsible tens of thousands of deaths every year. Finally, cars are so expensive for most people to afford. However, that doesn't stop low-income families from spending the most of their money to pay for the family car.
