I know it sounds stupid to even ask that, but my question/concern came from that for someone who is not aware of such a thing, after watching movies I would have never even thought to look for it had I ever been in such a situation. Referring to also the story above about the women who was stuck in the car.

So, if all is true, then the movies in this case are doing a serious disservice. I know sounds naive and stupid to even ask that but most things function mostly as they do in real life, this to me seemed an odd exception.
