Continuity mistake: During the vault chase scene, the vault spins on two separate occasions, tangling the lines in the process. The first time, it is being dragged out of the police station and the second when it destroys half a bank. The lines could not have been untangled, because both times they guys were turning to the right and the vault spins in the same direction. (01:40:30)
Continuity mistake: As the cars are being stolen from the train car, they're violently dropped onto the ground, yet they don't have a scratch on them. The best example is the vintage Corvette that Vin Diesel drives out of the train car. The car falls at least 6 feet, landing on the front left corner of the bumper, yet seconds later, the car is in perfect condition. (00:14:40)
Continuity mistake: Almost all the cars aren't with Brazilian plates. The plates here are always XXX- Where X are letters and numbers.
Revealing mistake: When Brian is racing the GT3RS through the mock up track we have a shot inside while he is doing a hard left. Look at the dash and the speedo on the far left is at 0 while the rev counter in the centre moves. Evidently he was stationary and just revved the car for the shot. (01:04:25)
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. (01:05:40)
