     Why are cars widely use in America? There are three reasons. I think, the first of all,

the country is very large and Americans enjoy make trips here and there. With cars they

can go everywhere. The second reason is what trains have never been as common in the

US than they are in other parts of the world. What's worse, Americans have to spend a

lot of money travels by plane. The third reason is most important one. Americans don't like

waiting forbuses or trains and even planes. They like cars because they want to travel fast

at some time to some places.
