Some inventions make a job easier.
Or they help us get more work done more quickly or for less money. The automobile did all that and more. Not many inventions have had such a big impact on people’s lives.
Cars changed how people got to work and how they relaxed. They changed where people lived, worked, played, ate, and shopped. Cars are the main reason our roads are smooth, since muddy gravel is a bad driving surface. Over time, cars led many Americans to move away from cities and into suburbs.
But not everything about cars has been good. Traffic got much worse, and so did noise and air pollution. And that’s not all.
