Automobile

An automobile (or motor car) is a wheeled passenger vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to seven people, typically have four wheels and be constructed principally for the transport of people rather than goods. However, the term is far from precise.

As of 2002, there were 590 million passenger cars worldwide (roughly one car for every eleven people), of which 140 million were in the U.S. (roughly one car for every two people).
