Cars Are the Most Important Transportation Tool In the United StatesCars are an important part of life in the United States. Cars have made the United Slates a nation on wheels.There are 3 main reasons why the car has become so popular in this country. First of all, Americans like to travel. The car provides the most comfortable and cheapest form of transportation. With a car people can go any place without spending a lot of moncy.The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the United States as they are in other parts of the world. Air-service provides a comfortable travel system. But it is too expensive to be used frequently.The third reason is the most important one, though. The American spirit of inde pendence is what really made cars popular. Americans do not like to wait for a bus, or a train or even a plane. They do not like to have to follow an exact schedule. A car gives them the frecdom to schedule their own time, and this is the freedom that Americans want most to have.
