Revealing mistake: When Gosling overtakes the car via the shoulder, you can see dust in front of his Mustang being thrown up by the camera car.
Revealing mistake: There is a large rip on the side of Charge's mask. It is supposed to be that his mask has been ripped. But you can tell that the mask was designed to look like it was torn, the effects of sewing are obvious.
Revealing mistake: When the movie starts, there's an aerial view of London's rooftops. The smoke coming out of the very first chimney doesn't move, revealing it's a painting.

Revealing mistake: When Carter puts the dead guy in front of the thing that blows your tires, right before he runs over him, the dead guy blinks his eyes.
Suggested correction: The blinking is too obvious to be a mistake by the actor, the scene is supposed to show that the man was still alive after being stabbed, as a final bit of suffering. Terribly unrealistic in real life, but not for this franchise.

Revealing mistake: When serving on the bridge, there are multiple shots where skid marks from previous takes are visible. (00:44:20)
