That was informative and already knew that might happen, but it was great to see things first hand.
One can argue weakly that there are other factors at work and they would be right. Not written in stone obviously at the same time there are a few exceptions to the bullets going through a car door.
Tractor over cabs might be a different story at times. The case of a LEO who emptied his .45 ACP into one in the side door that had a armed violent miscreant inside the vehicle. Not one bullet made it through the door. The LEO's partner had his .357 Sig pistol with him and emptied the .357 SIG pistol into the same door. All of the .357 SIG bullets penetrated the door and most of those hit the attacker inside as well. The bad guy was put out of the fight by the wounds suffered.
This is just one example only. There are a lot of what ifs and those don't matter in this case. They might in other cases.
