Corrected entry: At the beginning of a movie on the parking lot, we see Columbus fleeing by car from two zombies. When third zombie emerges on a back seat, Columbus crashes the car in an attempt to get rid of him. The size of a hole in the glass changes in shots, which kind of explains why the thrown zombie couldn't reach back into the car through the hole in the glass he just made by his own body.

Correction: Windshields are made out of a class/plastic "sandwich", after a body goes through a wind shield, the plastic "closes" the hole. Ask any Firefighter/EMS/Officer, the first time you see this you are amazed.
