Definition of automobile

Wikipedia defines automobile as
"An automobile or motor car is a wheeled motor vehicle for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles 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 word automobile comes, via the French automobile, from the Ancient Greek word (autos, "self") and the Latin mobilis ("movable"); meaning a vehicle that moves itself, rather than being pulled or pushed by a separate animal or another vehicle."

So automobile means a Self powered vehicle usually powered by an engine and runs on land, primarily used for transporting people from one place to another.
