Continuity: The windshield of David Corelli's car.
Audio/visual unsynchronized: When David is chasing the black car you can clearly see his airbag coming out with the second jump. In the next scene the airbag is gone.
Revealing mistakes: The woman who is hit by the car is pulled by a very visible wire.
Continuity: The blood stains on the black Ford Thunderbird's headlights change repeatedly between shots during the chase.
Revealing mistakes: Just after the black Thunderbird runs over Patrice for the second time, somebody yells "Hey, you asshole!" Just over a minute later, as the Thunderbird skids through an intersection, the same voice can be heard yelling exactly the same line in the same way, indicating a repeated audio clip.
Revealing mistakes: As Corelli leaves the crime scene at the beginning of the film, the black-and-white police car's large "SFPD" door emblem is an obvious cardboard fake; it has come unglued from the door and is curling up at the bottom.
