The Importance of Automobiles
Automobiles are vehicles that use an internal combustion engine, typically gasoline, to propel them. They are designed primarily for passenger transportation, but some models also serve as freight trucks or utility vehicles. The branches of engineering that deal with the manufacture and technology of automobiles are known as automotive engineering. The automobile has radically changed the lives of millions of people worldwide. It allows people to commute long distances at reasonable speeds, without having to worry about the unpredictable schedule of public transportation. It enables them to take longer trips, to visit relatives and friends at distant locations, and to work in cities or other towns for greater opportunities. The automobile also allows people to travel to sporting events or shopping malls, and to go on vacations with their families.
The modern car is a complex technical system with numerous subsystems that have specific design functions. Many of these systems have evolved from breakthroughs in existing technology, such as electronic computers and high-strength plastics. Others have been developed to meet new safety and environmental requirements, such as exhaust emissions control and airbags. Many automobiles are designed with several different fuel sources, including gasoline, diesel, and electric power. In the United States, Ford, General Motors, and Chrysler emerged as the Big Three automakers during the first half of the 20th century. They used mass production techniques and cheaper raw materials, such as steel and nonferrous metals, to compete with European manufacturers in a market that was much larger than their own domestic markets.
Today, the automobile is one of the most important components of our society. It has become a symbol of status, wealth, and freedom. Almost all households own at least one automobile, and a growing number own more than one. The invention of the automobile has had a major impact on the economy, both by creating jobs in automotive manufacturing and by stimulating the development of industries that produce raw materials for the vehicles and supply services such as gas stations.
Whether you choose a compact sedan that offers excellent handling and steering stability or a sporty hatchback with all-wheel drive, a great driving experience is within reach for everyone. In recent years, automakers have taken their penalty-box cars and given them the performance, interior quality, and technology that discerning buyers demand.
With a vehicle, you can avoid the problems of thousands of other passengers who must depend on public transport or taxi services. You can reach your destination quickly and comfortably, and you can carry a lot of cargo. You can even carry a bicycle or a motorcycle on some vehicles.
