SPOILER (don't read further if you haven't seen the movie)

During the scene when Sam Jackson's character shoots Robert DeNiro's character in the car, pay attention to the other cars you can see through the windshield.

You'll see :

1)windshield viewpoint : a line of cars, moving at regular speed

2)a really fast shot of something else

3)back to the windshield viewpoint : you can see the cars here are totally different ones! And the shot in-between was WAY too fast for the previous cars to have simply moved away.
