Continuity mistake: There are 16 women that have to compete to the death to become Navigators, it say "vie for 10 spots as Death Race navigators". But as the cars are lining up it says "Eleven drivers will compete over three brutal days". So does that mean 1 of the drivers doesn't have a navigator?
Continuity mistake: Niles York and Prudence drive in the tunnel with their car's headlights on. When the car stops the headlights are still on. As Prudence moves around the front of the car, the headlights are now off. There is a final wide shot of the car and the tunnel as they pass through a doorway and now the headlights are turned on again.
Plot hole: At the end, when billionaire Niles York is mistaken for Frankenstein, how is this possible? anyone who knows him can see it's him, from his appearance (burnt, but not 100%, his face still visible), his voice (doesn't sound like Frankenstein, but does sound like Niles York) & also a simple DNA test would have cleared up his true identity. When he goes back to Terminal Island, people would know it's a different person.
Visible crew/equipment: At the start of the first race, the camera focused on Katrina's ass as she is leaning inside the window of the car. As the camera pans to the right, crew members are visible in the reflection of the vehicle's black door. These are not to be mistaken with the crew of the Death Race television production present throughout this scene.
