Continuity mistake: After a long car chase about mid-way through the film, the camera pans over the highway littered with smashed cars and hundreds of cars piled up. In the middle of this, you see a van painted a little like the Partridge Family bus....definately a one of a kind van. Then you see footage of the car which escaped the chase going down an empty side street and passes the same van. No way there are two vans like this one.
Factual error: After the car chase in the film, as the car leaves a mess of vehicles behind it, it is obvious that the directional flow of the "props" traffic was on the left side of the highway, as if the film was shot in England. But it was shot in USA. The direction signs on this Los Angeles highway are also not visible to the traffic. Drivers would have to look back to see what exit they just missed.
Continuity mistake: When the tractor-trailer accident occurs during the chase, the two shots viewing the truck approaching the camera position have the red cab driving alongside the median and the trailer swung out to the driver's left, toward the road's shoulder. But when the film's heroes swerve to avoid the truck, the next shot showing their car crossing the median also shows the truck cab is at the shoulder with the trailer swung out toward the median- exactly the opposite of where it should be.
