Automobiles are motor vehicles that use a combustion engine to power them. They are usually four wheeled and can carry passengers and cargo. The automobile is one of the most important inventions of modern times. It has revolutionized world transport, allowing people to move more quickly and easily than ever before. It has also changed the way that families, friends and businesses interact with each other. There are many benefits to owning an automobile, but there are also some disadvantages. Cars cause pollution and can be dangerous if they crash or are stolen. They also often cause traffic jams in big cities. Many people also prefer to use public transportation when they can.
The first automobiles were steam-powered. They were heavy and slow. In the 1890s, Nikolaus Otto developed an internal combustion engine. This was an improvement over the previous steam engines that used coal or wood to fire a piston inside a cylinder. Car production in the United States began in the late 1890s. Henry Ford introduced new techniques that would greatly increase the number of cars produced. He set up assembly lines where each worker had a specific job and the car parts passed to them on conveyer belts. This allowed cars to be produced much faster and cheaper than previously possible.
By 1920 the automobile had taken over the streets and byways of Europe and America. Millions of people owned them. People from the cities could travel to the countryside. And people from the countryside could visit the cities. The automobile was a practical means of travel in the countryside but it was expensive and polluting.
During the 1920s the automobile became the backbone of a new consumer goods-oriented society. It provided jobs for millions of people worldwide. It was the lifeblood of the petroleum industry and a major customer for many other industrial products.
In 1982, it was the largest supplier of jobs in the American economy, employing about 1 out of every six workers. It was also the world’s largest purchaser of steel, copper and aluminum. Its demands transformed the technologies of ancillary industries, particularly those producing raw materials.
Modern life is impossible without the automobile. The automobile has brought people closer together, allowed them to work and play outside the home and to spend more time with family and friends. In addition, it has created more jobs for those who make or repair them.
The automobile has become an integral part of our daily lives. Its convenience has made it a necessity for most of us. Its negative effects, however, cannot be ignored. Many people are killed or injured in crashes each year. Traffic congestion causes people to lose time. The combined exhaust from millions of automobiles causes air pollution. And there is limited parking space in cities.
