I don't know where people get this notion that if you shoot at a car windscreen that the bullet is going to bounce of. In some circumstances it will but i wouldn't like to rely on it if i was sitting in a car with someone shooting at me. That's why they invented bullet glass. Below An incident that happened here a few years ago.
Mr Colwell was the driver of a stolen BMW which was facing the officer with its engine revving, in what appeared to be an attempt to escape a vehicle checkpoint, having ignored the officer's commands to stop. Police officer fired two shots. The first went through the windscreen and the second through the driver's window.
Mr Colwell got out of the car and collapsed.
Despite the efforts of medical personnel, he was pronounced dead at the scene.
PS. You would wonder how this happened when the bullet used was 9mm and not .40 or .45.
