1904 was also the first year of the United States national championship, which was awarded retrospectively to the winner of the Vanderbilt Cup race in Nassau County, New York. It was in the process of seeking official standing for awarding the Championship that the AAA established the authority of CARS as a motorsport sanctioning body.
