The United States is full of cars.There are still some families whithout cars,but some families have two or even more.
However,cars used for more than pleasure.They are a necessary part of life.
Cars are used for bussiness.People drive them to officer and factories.When salesmen go to different parts of the city,they have to drive in order to carry their products.Farmers have to drive into the city in order to gei supplies.
Sometimes small children must be driven to school .In some cities school buses are used only when children are too young to walk that far,their mothers take turns driving them to school .One mother drives on Mondays,taking her own children and the neighbors'children as well.Another mother drives on Tuesday,another on Wednesday ,and so on.This is called forming a car pool.Men also form car pools,with three or four men taking turns driving to the place where they all work.
More car pools should be formedin order to have fewer cars on the road and to use less gasoline.Parking is a great program,and so is the traffic in and around cities.Too many cars are being driven.Something will have to be done about the use of cars.
