I've had occasion to work beside special effects guys in movies.
Glue stick is the standard projectile for doing the bullet / buckshot-through-the-windscreen sequence.
The glue stick is fired from a purpose built air cannon INSIDE the car. The (special movie) glass blows away from the driver and the glue stick melts from impact and sticks the potential shrapnel together. A neat, safe solution. DON'T TRY THIS AT HOME.
