Doc Hudson, also known as The Fabulous Hudson Hornet, was a former dirt track racer who, prior to his death, served as the judge and doctor of Radiator Springs, as well as Lightning McQueen's mentor.
Doc Hudson is a car of few words but many talents. He not only serves as the town judge, he's also Radiator Springs' resident doctor. Doc is respected and admired by the townsfolk for the way he looks out for their health and tends to their aches and pains. No one knows too much about Doc before he came to town. He keeps his private life private. But if you've got a bad spark plug or a rattle in your engine, his door is always open.
