After 1945, the US government built many new roads and highways. People moved farther and farther from the cities where they worked because they could drive their cars on these new roads from their suburban homes to work in the city. Some of the big car makers also bought the electrified transportation systems and destroyed them. As people stopped using public transportation, cities spent less money fixing old buses and trains or buying new ones. Public transportation got worse and worse.
       In the late 1960s, people found out that the increase in the use of cars led to many problems. There were always too many cars for the highway system, and terrible traffic problems developed. People were spending hours in traffic jams getting to and from work every day. In addition, the air in many cities became dirty because of pollution from millions of cars, and many people died in traffic accidents. As people began to get worried about how the use of cars was hurting the environment, cities began to spend more money on public transportation again, so fewer people would have to drive cars.
