Continuity: Towards the end of the film, the bus that Jim sneaks on to changes from two rear axles to one.

Revealing: When the two police cars flip over if you look close you can see that at least one of the people in the car is a dummy. The one dummy is wearing a hat that appears to stay on his head even when the car flips.

Continuity: During the scene where Ryder has a knife to Jim's throat and is asking him to repeat "I want to die", you can see through the passenger window behind Ryder that morning is starting to break. About a minute down the highway when Jim and Ryder come upon the construction zone, it is now black as night again.

Continuity: When Jim is driving along the road, the car with the boat on the back passes him. When John appears, Jim pulls out onto the other side, and the road is just flat with sand and grass, yet when it cuts to a face shot of Jim there are now large mounds of mud, or something, at the side of the road.

Continuity: In one scene C. Thomas Howell almost runs head-on with an 18 wheeler, but just misses it. However, the truck clips the car he is driving and clearly takes the bumper clean off. The next driving scene shows the bumper back on the car.
