12、First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation. With a car people can go anyplace without spending a lot of money.The second reason why cars are popular is the fact that the United States neve
13、r really developed an efficient and inexpensive form of public transportation. Long- distance trains have never been as common in the country as they are in other parts of the world.
