Factual errors: Several shots show the police scanner in Kowalski's car as he is listening to the police talk about him. The scanner's LED lights are shown blinking. In this mode a police scanner is silent since it is "scanning" frequencies. If the scanner were receiving a police transmission only one LED would be lit steadily.
Continuity: Interior shots of the Challenger at various times through out the movie show different dash designs. Early in the movie, we see a standard 3-spoke wheel with the 5-hole standard gauger cluster. Later, we see a Rallye gauger cluster with a Rim-Blow style wheel. These items swap back and forth until the end of the movie when once again, we see the Rallye Speedometer at 140mph.
