Continuity mistake: In the scene where Cannonball is driving the Mustang and Redman is driving the Charger through the incomplete Interstate, they begin bashing each others' cars to bits. Several shots show the badly damaged cars and the results of the multiple hits taken. However, when we are shown the cars just before the bridge jump sequence, neither car appears damaged.
Factual error: Supposedly the Pantera was rigged to explode once it reached 160 mph. There are two problems here. First, a stock Detomaso Pantera could never reach 160, especially a smog-controlled "L" model with the old bias-ply Arriva tires, which is what they used in the movie. Second, the Dodge Polara police car that was tailing him closely and matching his speed, most DEFINITELY would not be able to achieve that speed.
