Revealing mistake: At the start, just as Moreau rides up the stone road leading to the monastery up ahead, before he passes the two guards we can see that it's a flipped shot - note the backwards license plate number.
Continuity mistake: During Nadya's escape from the monastery, there are exterior shots of Nadya through the windshield and there's nothing hanging from the rear-view mirror, but in the interior shot (viewed from the back seat) just as she swerves away from the red car, there's a small cross on a cord which is hanging from the rear-view mirror.
Answer: The entire film was designed to have a different tone and feel from the first film, to be accessible to viewers who never saw the original. Thus this film exists as something of a soft reboot. In interviews the directors also stated the origin story for Ghost Rider never made sense to them and they wished to change aspects of the character for this film. That includes removing the Penance Stare and making Ghost Rider have an uncontrollable desire to feed on the wrong people have committed, even things like little white lies could set him off.
