The automobile's impact on American life is everywhere,for the car is much more than a means of traveling from one place to another.(1)___________________________________.Today we'll look at some of the negative effects.Traffic, road systems, traffic lights, parking lots, gas stations,car washes, fast food restaurants, malls, superstores, subdivisions—so many of the elements of our lives and worlds are the result of the automobile.A number of sociologists blame the automobiles for the decline of the downtown areas of the major cities.In the 1950's and 1960's the automobile made it possible to work in the city and yet live in the suburbs many miles away.Shopping patterns changed.
