The truly odd thing here as opposed to the laminated glass is that the bullets seem to stay more or less on the path they are on when they hit the door, not deflecting like they did with the laminated glass.

And as you can see in the photo, the fact that the bullets did not penetrate the passenger door is of little comfort if you are inside the vehicle...

What about the door window glass?

Utterly inconsequential ballistically.

Anything will shatter it without causing any bullet damage, even a .22.

To demonstrate the difference here, a 60 grain .22 LR fired from inside the vehicle won't even penetrate the windshield.

That same round can pass through BOTH side windows without even slowing down.

Again the question must be asked...

What happens if you pepper roughly the same area with several rounds?

Again, the 9mm is called in to see what happens.

Here's the results.

Pay particular attention to what happens on the other side of the passenger door.

Yup! Penetration.

Lessons learned:
1. A single car door offers NO protection against handgun rounds.

2. Even two car doors and the passenger compartment offer little protection, and even that protection can be expected to evaporate when multiple rounds are fired.
