Automobiles have changed the way we live. They are highly complex technical systems. They consume natural resources, pollute the air, and cause problems. Thankfully, the industry is working on developing alternative power sources for future cars.
One of the first industries to use assembly lines was the automobile industry. This made cars more affordable for middle-class families. The automotive industry grew rapidly during the first half of the twentieth century.
In the United States, the gasoline-powered automobile swept the streets by 1920. This was due in part to increased economic development and a higher per capita income. The car industry rebounded after World War II and introduced new features.
