You never know when you could find yourself in a dangerous survival situation where you need to know how your immediate environment could protect you. In this Buick O’ Truth article put out by the Box o’ Truth, the penetrative capabilities of pistol rounds are examined.
A lot of officers have been trained to conduct a high risk stop behind the “cover” of their door, leaving it open while they kneel behind it with their weapon drawn.

ALWAYS err on the side of safety, ESPECIALLY when you are shooting at the metal parts of the car.
