Corrected entry: When Frank is looking at the picture of his daughter he rips one big piece, but when the camera pulls away you see him drop one piece then rip another piece and let them fall. Back zoomed in, only the one big piece is missing.
Corrected entry: When explaining about the car, 'Coach' points at the twin guns on the cars hood saying "and twin 30mm, belt-fed machine guns for offense". Looking at the guns one can easily say that those are not 30mm guns. Such guns are mounted on anti-tank aircraft and measure few meters in length, plus of course have much wider barrels. the guns on the car are at best 30 caliber ones, which is 7.62mm.
Corrected entry: It's established that whenever Machine Gun Joe kills another racer, he cuts his face in the "tick mark" style - four vertical marks followed by a horizontal one (as his scars show.) After killing Grimm "Reaper," he is shown making a horizontal mark, but the leaderboard in subsequent races shows his kill count as something that's not a multiple of five (and he didn't score any more kills in the meantime, remember).
Correction: It's established that every time Machine Gun Joe kills, he adds a mark, however, it doesn't state whether it's on the track or not. So it cannot be viewed as a mistake since he could have killed off the track.
Corrected entry: Ames, in his Frankenstein race suit, jumps out of the car at the end while Case continues driving. When Frankenstein is apprehended, Case is wearing Ames' race suit.
Correction: After Frank jumps out of the car it shows a second suit in the seat next to Case.
Corrected entry: Frank covers Colt's car in napalm, which is then ignited by a thrown cigarette lighter. Colt is engulfed in flames and dies after getting hit by Machine Gun Joe. A car cigarette lighter would not ignite napalm. Napalm burns at extremely high temperatures, typically between 800 to 1,200 °C (1,470 to 2,190 °F), while a car's cigarette lighter produces a much lower heat. The lighter's flame is not hot enough to initiate combustion of napalm's gelling agent and volatile petrochemical mixture.
Correction: The temperature at which napalm burns once it's alight isn't the same as the temperature needed to ignite it in the first place. Gasoline (often used in napalm) will ignite at about 280 degrees C (so napalm is similar), but then burns at over 1,000 degrees. A car cigarette lighter easily gets hot enough to ignite gasoline and napalm.
Correction: Actually, "Frank" rips off the large upper left corner of the picture (with the other man holding his daughter), AND the bottom right corner of the picture.
