life hammer

 A pencil size window breaking tool could be installed in the inside of a car where the side mirrors are bolted.  the mirror where attached always has a plastic cover plate.  a simple hinge on the cover plate that can be popped open id a car is underwater.  One on each side in the front seat.  Low tech method to get out of a car underwater.   The high tech method would be to have a pressure senor in the side mirror.  If the sensor activates the mirror cover would pop open and access to the window breaking tool is ready to break the window.
