One of the traditions of the Indy 500 race, incorporated into the game, sees the winner swigging a triumphant bottle of milk in Victory Lane. In 1993, Emerson Fittipaldi (who also won the 1989 race the game is based around) infamously consumed orange juice instead - not for dietary or ethical reasons, but to promote his ownership of several orange groves in Brazil. He was ridiculed and booed for this, particularly at the next IndyCar race at the Milwaukee Mile in the prime dairy-producing state of Wisconsin, and remains the only driver since 1955 not to celebrate with milk.
Many consider this the first auto racing simulation based on realistic driving behavior, but REVS (1986), developed by Geoff Crammond, already introduced this in a game.
