should carry a center punch in their cars just in case you car gets
submerged in water. Use the center punch on you side windows to get out,
otherwise it would be impossible to open the door....
Although I can't dispute this idea, I've been curious exactly how hard it
really would be to open a car door under water. You have air pressure
inside the car trying to escape, and although the door would be slow, it
shouldn't cease to open.
If you tried to open the door, it would indeed be impossible to open it.
Depending how deep you were, there would be (many lbs/sq in)*(door
surface area).
however, that is the wrong solution.
Roll down the window. then go out.
