Continuity mistake: When Kenny Rogers gets trapped in the rest room at the beginning of the film, he pulls the knob out from the door. When this happens, the knob is on the left side of the door from his point of view. After he climbs out the window, the door has changed to having the hinges on that side and the style of the door does not look like it has a knob at all. A rest room this size would only have one door, so it has to be the same door.
Visible crew/equipment: When Kenny Rogers steps out of the RV before the final race, a camera man is visible through the reflection of the RV's door.
