Automobiles are motor vehicles that are used to transport people. They have four wheels and can be powered by an internal combustion engine or electric motors. They are often designed to hold a driver and a small number of passengers. Vehicles devoted to cargo are usually called trucks, buses, vans, or limousines. The term automobile derives from Ancient Greek autos (self) + Latin mobilis (moving). The modern automotive industry has become a major force in society. It provides jobs and economic growth, and it influences consumer tastes and trends. It also influences many ancillary industries such as steel and petroleum. The automobile has changed lifestyles and has contributed to the development of cities and suburbs. It has also brought negative effects, such as air pollution and a drain on world oil supplies.

The scientific and technical building blocks of the modern automobile go back several hundred years. In the late 1800s, engineers developed steam engines and electric power to move cars over the road. Karl Benz is credited with inventing the first gasoline-powered automobile in 1885. By the 1920s, the automobile had overtaken the streets and byways of Europe and America. It became the lifeblood of a new consumer-oriented economy and was one of the leading users of steel, petroleum, and other industrial products. It also impacted culture and society, setting new fashion trends and creating leisure activities such as amusement parks and fast food restaurants.

Modern automotive engineering has made significant advances in the quality and safety of vehicles. Safety features have included seat belts and air bags. Other innovations include electronic control systems that manage ignition timing, in-car entertainment and navigation. New technological developments are constantly being introduced to improve the performance and reliability of automobiles. For example, computer-based control systems can replace physical linkages between pedals and the throttle and brake mechanisms, as well as monitor the health of the engine.

Owning a car gives people freedom and independence. They can travel to work, school and social activities without relying on others for transportation. It is especially useful for people with disabilities or those living in remote areas. Cars also provide the opportunity to shop and visit friends and family in other towns.

Time is a precious commodity, and having an automobile frees up valuable time by reducing the need to wait for public transit or travel long distances on foot. It also allows drivers to spend more time on the things that matter most in their lives.

Owning a car is an important investment that demonstrates to lenders that you can make regular payments on a loan, which may influence your ability to buy other goods or services, such as a home. It is also a status symbol that shows others your wealth and lifestyle. For many, it is a way of expressing their personality through the design and color of their car. There are many other benefits to owning a car, but these few highlights will give you a good idea of why the automobile is so popular.
