A car is a motor vehicle wheels, self-propelled and used to transport a product from the automotive industry. Most definitions of the term specify that automobiles are designed to operate primarily on roads, which must be from one to eight people, who typically have four wheels with tires and be constructed primarily for the transportation of people rather than goods . The year 1886 is considered the year of birth of modern automobiles. In that year, the German inventor Karl Benz built the Benz Patent-Motorwagen. Cars have not become widely available until the early 20th century. One of the first cars that was accessible to the masses was the T model in 1908, an American car manufactured by Ford Motor Company. Cars were quickly adopted in the United States, where cars and animal-drawn cars have been replaced, but it took much longer to be accepted in Western Europe and other parts of the world.
The cars are equipped with controls that are used for driving, parking, passenger comfort and safety, and control a variety of lights. For decades, additional features and controls have been added to vehicles, making them increasingly complex. Examples include back-up cameras, air conditioning, navigation systems and in-car entertainment. Most service cars in the 2010s are powered by an internal combustion engine, driven by the combustion of gasoline (also known as gasoline) or diesel. Both fuels cause air pollution and are also accused of contributing to climate change and global warming. Vehicles that use alternative fuels such as flex fuel vehicles based on ethanol and natural gas vehicles are also gaining popularity in some countries. Electric cars, invented in the early history of the car, began to be commercialized in 2008.

The use of car expenses includes the costs of: vehicle acquisition, interest payment (if the car is financed), car repair and maintenance, fuel, depreciation, driving time, parking fees, taxes and insurance .

The capacity of the human being to move flexibly from one place to another has profound implications for the nature of societies. It was estimated in 2010 that the number of cars has increased to over 1 billion vehicles, up from 500 million in 1986. The number is increasing rapidly, especially in China, India and other newly industrialized countries.
