So say your driving your car over the bridge and you have the situational awareness to realized that "Holy shit that ship is going to hit the bridge." or realize that the ship has hit the bridge and you're going into the drink, what do you do? I've heard of people going into the water in their vehicle and not being able to open the door to get out, or not being able to roll down the windows due to a shorted electrical system, so what do you do? Stay belted, roll down front windows, and hope the car is nose heavy and an air pocket will form in the back half of the cabin, (Sedan or 4-door truck), hit the water and climb out the open window to swim to the surface...in this case, in 47* water.
Any of you survival experts out there have another idea. (Not you Yota Up, you don't know shit about fuck).
