Continuity mistake: The Google Earth Streetview route shown through downtown Chicago (I-94/90) is not part of the computer-plotted route from O'Hare Airport to Ishpeming which they used. It would have been a long detour from the suggested path laid out for them. (00:34:30)
Continuity mistake: In electric avenue scene, the number of wood bars the cast has to go around changes from two to four.
Factual error: At the conclusion of the film it is stated on screen: "Ayrton Senna died aged 34. In the aftermath of his death, the FIA appointed Ayrton's friend Prof. Sid Watkins to improve safety in Formula One. There has not been a fatality in Formula One since." While it is true that no driver has been killed at a Formula One Grand Prix since Senna, there were crashes at the Italian Grand Prix in 2000 and the Australian Grand Prix in 2001 which resulted in the deaths of marshals.
