In Pixar's Cars, Doc Hudson owns the Radiator Springs racing museum.
Doc's museum displays trophies and memorabilia from his earlier career as the Fabulous Hudson Hornet. He initially hides that history from Lightning McQueen because he dislikes the attention and does not want to relive the disappointment of being pushed aside after an injury.
Doc eventually becomes McQueen's mentor, teaching him how to turn effectively on dirt and how to understand racing beyond speed. His relationship with McQueen gives the film its central generational story: a former champion helps an ambitious newcomer mature.
The museum is sometimes confused with the town's other businesses, such as the Cozy Cone Motel or Ramone's House of Body Art. Doc is also the town's physician and judge.
