Knowing how to escape from a submerged vehicle is one of those skills you hope you never need. Fortunately there’s an easy way to escape if you can remain calm.

You may try to break the glass, but that’s easier said than done. In a panic, many people will hit the center of their window when they should really aim for the corner. See why the location of your hit matters for tempered glass in the video below.
