Let's say, for the sake of argument, that you're driving down the road. You see an animal trying to cross so you swerve out of the way, spinning out of control, and end up splashing down in a nearby river or lake. For whatever reason (water pressure or otherwise) your doors are locked and your windows are rolled up. What do you do? Here's how to use your head rest to escape. It's now how to use it as you think.

And now you know. If this saves your life, leave me a comment, will ya?
