Continuity mistake: During the sequence where Kowalski is being chased through the mining buildings, there's a shot where the passenger-side mirror gets knocked off the car by a jutting pole, and the camera tracks it to breaking on the ground. But the next shot showing that side of the car shows the mirror. It keeps appearing and vanishing for the rest of the scene (when it's not there, there's no sign of damage to the car: the car used for those shots appears to never have had a wing-mirror).
Factual error: At the end of the film, The Voice tells his radio audience the Challenger was estimated to have hit the bulldozers at 185 MPH. The top speed of the Challenger, with a 426 Hemi, was 145 MPH. A trained police officer (and there were many of them there), even estimating speed without a radar gun, would be able to estimate the speed much closer than that. It's part of their training to be able to make estimates that will hold up in court, and 185 MPH is noticeably different than 145 MPH.
