IF it comes down to life and death, I am going to bash that gun against the window…… I might shoot underwater who knows. I understand roll window down but most cars have electric windows, I would assume some electrical problems in any water containing ions. The point is I know where that dense piece of steel is, on my belt, not in the back corner of the glove box, or tossed across the car like a hammer or other unit might be. Maybe I wont be able to get to it if hurt, but I will have my seat belt on and the government knows what is best for me so I should be okay.
And as far as screaming and bleeding if stuck in a machine, this is THR strat and tact forum, I expected somebody to say they would be in shock and the pain would not hurt them, they would separate their shoulder (if arm stuck) allowing greater mobility, tap 2 rounds into motor housing, pull out 1 of 3 knives on person cut though steel to remove arm with super knife…… sew limb back on with cat gut, give self tetanus shot.
Call for help is a good suggestion that slipped my mind.
