The private car has long played an important role in the United States. In 1971 eighty—three percent of American families owned at least one car, and twenty--three percent had more than one. By giving workers rapid, convenient transportation, the car has freed them from having to live near their place of work. This has helped develop the growth of the suburbs, but it has also led to traffic problems in the city. In addition, the car has caused neighborhood ties to be weak by making it easy to keep up friendship at a distance and to enjoy leisure activities far from home.

For farm families the car is a great comfort. It has relieved their loneliness, making it possible for them to travel to town frequently for business and for pleasure, and also to transport their children to distant schools.

Family life has been affected in various ways. The car helps to keep families together when it is used for picnics, outings, camping trips, and other shared experiences. However, when teenage children use or own one, they can easily escape from their parents. For some--young or old--using a car leads to dangerous traffic accidents caused by carelessness or by deliberate breaking of driving laws. In 1971, over 5,000 people were killed in car accidents in the U. S., and many more were injured. This number has been somewhat reduced by the gas shortage which has decreased driving to some degree and has also lowered the speed limit.

For many Americans the car is something necessary as well as convenient. But for some, it is also a mark of social status, an important middle--class symbol, and for young people, a sign of becoming an adult. Altogether, cars mean much to Americans.
