The wheeled motor vehicle used for transportation is a car or automobile. Most car descriptions state they travel primarily on highways, seat one to eight persons, have four wheels, and transport individuals rather than goods primarily. A broad variety of companies and organizations engaged in the design, development, production, marketing, and sale of motor vehicles are part of the automotive industry. It is one of the largest economic sectors in the world by sales. The automobile industry does not include businesses, such as automotive repair shops and motor fuel filling stations, devoted to the servicing of cars after the sale to the end-user. The word automotive, referring to any type of self-powered vehicle, comes from the Greek cars (self), and Latin motivus (of motion). As suggested by Elmer Sperry (1860-1930), this concept first came into use in 1898 with reference to automobiles.
