Factual error: At the end of the movie the 1970 Challenger R/T that is shown crashing into the bulldozers is actually a 1967 Chevrolet Camaro at the time of impact. It's visible for just a few frames, from behind at impact (before exploding) and later as it stands on its nose, after the fire is put out. Note the plain steel wheels, painted silver in the latter shot.
Super Soul: This radio station was named Kowalski, in honour of the last American hero to whom speed means freedom of the soul. The question is not when's he gonna stop, but who is gonna stop him.
