There is no way that Number plate of the car of Granddad Chava coming out on colliding with mom of Chupa. All four holes were intact, there were not torn or cracked or anything for the 4 bolts to get loose. There is no way of an animal colliding to the car from the front that will put enough force at correct places to make a properly secured number plate come unstuck. The director/ scriptwriter couldn't think of some plausible method of making Quinn come to know about Chava and his location.
