Everyone knows that the car the two main characters are driving is a stick shift, even the editors. Almost right after the demon eats the cop's tongue, the two characters freak out and get in the car and start driving down the road. About one-three clips later, the girl is showing no emotion and the sound editor put in a gear shift change sound, yet she does not change gears. You can tell she does not because you see her arm and hand on the shifter.
