AUTOMOBILE vs CAR

The word automobile was originally coined by the French, and comes from the Greek "autos" (self) and Latin "mobilis" (moveable). Car has roots that go back to Latin as well- "carrus" or "carrum" meaning "wheeled vehicle", which has come down to us as cart, carriage, and chariot, to name three examples.

I knew someone would have an answer. Sounds good to me.
