Factual error: When Rusty Nail is chasing them down the dirt road, and they come to a nearly 90 degree turn, there is NO way that a semi could take that turn at the same speed as the car and not flip over.
Suggested correction: The turn wasn't a 90 degree angle, it was more of a curve than a turn.
Factual error: In the scene where Lewis dials the police at the gas station, he says "Rawlins County Sheriff's Department please." There is no such county in Wyoming (where this particular scene is) named Rawlins County. He should have said Carbon County. Also, Table Rock is in Sweetwater County, and there are no police services there. (00:36:50)
Suggested correction: Many films and TV shows make up their own places.
Except in this film they're using real town names and they show a real map.
Plot hole: Fuller is supposed to be heading to Denver, but after picking up Venna in Boulder he inexplicably stays on even after telling Lewis just before this that he was not going to be going home with them.
