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.
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.
Chosen answer: The poker chips give the bills a more realistic texture by striking them while spinning, so they don't look newly made.
