Automobiles are a fundamental mode of transportation, used by approximately 1.4 billion people around the world. About one-fourth of these vehicles are produced by foreign companies. Automobile manufacturers are continuing to innovate and produce new designs and models. Today, around 70 million new passenger cars are produced every year. Automobiles have evolved into a sophisticated technical system with thousands of component parts. They have evolved as a result of advances in existing technology, new technologies, safety legislation, and competition among manufacturers.
There are several definitions of automobiles, but all of them are essentially four-wheeled, self-propelled vehicles used for passenger and goods transportation. Automobiles also include motorcycles. While motorcycles don’t meet all the definitions of an automobile, they are still considered a vehicle when they are designed to carry more than one passenger.
A motorcycle is a three-wheeled motor-driven vehicle with a seat for a rider. The motorcycle’s motor must displace 150 cubic centimeters (cc). Currently, you need a Class C driver’s license to operate a motorcycle, and an M-1 endorsement if you’re driving a motorcycle with a sidecar.
The automobile revolutionized everyday life in the United States, and helped people access jobs and more personal freedom. It also helped create a new type of society. Automobiles allowed mass production and lower prices for consumers. However, the widespread use of automobiles put stress on American families, who had less time to spend with their loved ones.
