Movie Goof (factual errors): When the action is cut with the German weather report, all captions are in German except the one that says "tomorrow".
Movie Goof (continuity error): When Joe is chasing Jimmy through the streets of Chicago, a helmet can be clearly seen on the driver of the red car (Joe's car) as it enters the tunnel. Both drivers are shown before and after without helmets on.
Movie Goof (continuity error): In virtually every scene where someone is walking through a crowd, the people around the main characters change from shot to shot.
Movie Goof (continuity error): During the race in Germany (the one with the rain) it is sunny in several shoots, although it is apparently "raining" and streets are "wet".
Movie Goof (continuity error): Jimmy and his brother get in a Mercedes S Class to drive away but the inside dialog was filmed in a Lincoln Town car.
Movie Goof (errors in geography): Some of the racetracks are clearly doubling as others on the tour, and even when the correct location is used there are often obvious hints that some shots were taken elsewhere. Some shots of "Tokyo", for instance, are very obviously of Chicago and Toronto, and yellow cabs can be seen in Germany where taxis tend to be eggshell colored.
Movie Goof (continuity error): While performing the "coin trick", Tanto picks up coins with his left rear tire, but once he pulls into the pits all three coins are on the right rear tire.
Movie Goof (revealing mistake): When they park the cars after the last race, the tires on the car in front are new with no wear at all.
Movie Goof (factual errors): In the scene where the drivers are rescuing Moreno in the lake, flames are clearly visible on the water. Methanol fuel, as used by CART, burns with an invisible flame, and is water soluble. Water is actually the preferred extinguishing agent for methanol.
Movie Goof (continuity error): Jimmy's hair by the pool, sometimes in his eyes, sometimes brushed aside.
Movie Goof (audio/visual unsynchronized): During the first race at Chicago, we hear Paul Page (III), a well known CART and IndyCar commentator, describing the race. However, the following shot of the TV booth shows two men, neither of whom is Page.
Movie Goof (continuity error): Sophia enters nightclub in a lacy top with nothing beneath. In the next cut she has the lacy top in her hand, but now has a black blouse on where there was none before.
Movie Goof (revealing mistake): One of the "photographers" at the media event is taking photos without a lens attached to his SLR camera body.
Movie Goof (factual errors): First CART race in Germany was driven in 2001, but Juan Pablo Montoya was already a Formula One driver in this year.
Movie Goof (factual errors): Clearly, the race in Germany was americanized for the movie. Commentators would not say "Welcome to Germany", but "Welcome to City, Germany". In addition, German TV does not announce temperatures in Fahrenheit, ever. And German weather maps show Germany, not half of Europe for their forecast. If they do, the countries are named in German, not English. In the movie, the temperatures are in Celsius and Fahrenheit and the weather map shows 'Poland', not Polen, 'Germany' and not Deutschland.
Movie Goof (continuity error): After the last race, Joe Tanto takes off his driving gloves, which are clean, and reveals dirty hands meant to be a result of the race.
Movie Goof (revealing mistake): When Tanto does his quarter trick, the quarters are pressed into the tires seem to be in good condition. After being driven on, the features should have been abraded by the road surface making them look like blanks instead.
Movie Goof (continuity error): In many scenes, the cars switch between a speedway wing setup and a road course wing setup within the same race.
Movie Goof (factual errors): In the end credits, Jasmin Wagner's name is spelled as Jasmine.
Movie Goof (continuity error): At the final race, the announcer says that Bly, Brandenburg and Tanto helped save Moreno even though Tanto sat in the pits the entire time (this possibly has something to do with that scene being rewritten as stated in "alternate versions").
Movie Goof (continuity error): The onboard camera behind Jimmy Bly's head in the first race appears and disappears between shots.
Movie Goof (factual errors): Joe and Jimmy could not have taken the race cars from the party as easily as they did. CART cars do not have onboard starters, so they can't be started simply from the cockpit. You would need a crew member with a starter motor at the back of the car to fire the engine. Most "racing cars" at shows and parties like this are usually dummy display models, without "real" engines or other heavy, and expensive, mechanical components. Moreover, if the cars actually had been authentic (and somehow could have been started), they likely would have had virtually no fuel aboard; most city fire departments have strict regulations on this for a show or display car, especially inside a hotel.
Movie Goof (factual errors): In the end credits, Michael Andretti's name is spelled as Micheal.
Movie Goof (continuity error): After Jimmy and Beau has saved Memo from the explosion, Memo's car is clearly seen in the water, lying in the same position as when they dragged Memo out of it, showing that no parts of the car has been blown up.
Movie Goof (factual errors): There are several errors in the depiction of CART cars, their equipment and configuration, and the racetracks they use.
Movie Goof (factual errors): Methanol, the fuel used in CART racing cars, does not float on water as gasoline does - alcohol will mix very happily with water. It also burns with a barely visible flame, unlike gasoline which burns with the yellow flame and thick black smoke shown in the film.
