Automobiles
Automobiles are vehicles that travel on land, have four wheels, and use an engine for power. They are often used for personal transportation, and can carry a number of people. An automobile is a type of car, although it may also refer to a truck, minivan, bus, or other larger vehicle. It may have a passenger compartment, or it may be designed to transport cargo only. The scientific and technological building blocks of the modern automobile date back several hundred years. The automobile has become one of the most important consumer goods in the world, and is a significant economic force in developed economies. The automobile is an important source of income for automotive companies and for ancillary industries such as petroleum and steel.
In the United States, automobile manufacturing is a major industry, and the country is known as the “car capital of the world.” The nation has a large population and a huge territory to cover, making a good market for automotive transportation. Cheap raw materials and a long tradition of industrial engineering encouraged the mechanization of automotive production. American inventor and businessman Karl Benz invented the first automobile around 1885, and other engineers refined his invention. By 1920, cars had become commonplace in the United States. The automobile revolutionized America’s economy, as it became the primary means of family transportation and drove growth in other industries, such as retailing.
The automobile gave Americans access to jobs and places to live, and it contributed to leisure activities such as traveling, sports and entertainment. It also led to the development of many new services, such as hotels, restaurants and gas stations. But the automobile was not without its drawbacks, such as pollution from exhaust and the loss of undeveloped land to highway construction.
In addition, the automobile introduced changes in lifestyles and brought new social problems. The proliferation of cars created congestion on roads and highways, and the safety problems associated with cars led to new laws and government requirements, such as seatbelts and driving licenses.
A car is an expensive investment, but it is one that can offer a great deal of freedom and flexibility. People can travel where and when they want, and can shop for whatever they need, as they do not have to depend on public transportation or rely on others to get them around. Moreover, they can move large items from place to place, something that cannot be done with a bicycle or a bus. The automobile has largely replaced other forms of transportation, and it is expected to continue to do so for decades to come. The United States currently has more than 1.4 billion cars in operation, and the average American drives over three trillion miles (five trillion kilometers) per year. The majority of these vehicles are passenger cars. Cars are available in a variety of styles and sizes, with each offering different features to fit specific needs. Some of the more popular are coupes, sedans and SUVs, which offer a combination of passenger and cargo space.
