Continuity mistake: When O'Connor blocks the bus on the two-lane highway with his vehicle, the bus swerves around his car towards the shoulder, clips the right rear of the car, and breaks the vehicle's rear window. In the next shot, the bus reverses angles, flips over the left rear of O'Connor's car nearest the center line, becomes airborne, and then rolls over and over down the center of the highway. If it had continued on its initial trajectory, it would have crushed his vehicle and continued onto the shoulder.
Other mistake: In the scene where Toretto and Hobbs are fighting, the fight is so violent that Torettos eyes are run through glass, faces are smashed into concrete and beat endlessly. Yet when the fight is over, the next scene shows both with not so much as a mark on their faces.
Continuity mistake: The hole in the plastic which is around the vault Han ordered changes after Tej says "You got a 100 million dollars in a safe, are you going to put somebody else's handprint on it?" This is easiest to spot around the palm scanner: at first, it is completely free, but after that line, the plastic suddenly hangs in front of it.
