A car is a wheeled, self-powered motor vehicle used for transportation. Most definitions of the term specify that cars are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. The year 1886 is regarded as the birth year of the modern car. In that year, German inventor Karl Benz built the Benz Patent-Motorwagen. Cars did not become widely available until the early 20th century
Cars are equipped with controls used for driving, parking, and passenger comfort and safety. New controls have also been added to vehicles, making them more complex. Examples include air conditioning, navigation systems, and in car entertainment.
