I don't know what the roads are like where you are, but on some of the long isolated stretches of road I travel on( especially in winter) accidents usually involve smashed, overturned vehicles which have hit black ice and either hit another vehicle head on, or skidded off the road to hit a tree or slide down an embankment. On any Canadian Highway there are frequent collisions with Moose or deer and these are normally very serious if not fatal. At any rate, the accidents are more than the fender benders usually found in the city. If the Dammed person wasn't in any danger as you put it, then they would be able to open the door and walk out themselves. The Trauma kit is something that I designed to put in my vehicle in the event that I happen across someone who has suffered TRAUMA. This alone might indicate that they are in danger. If you can open the door of a car that is smashed, upside down and in three feet of snow using "muscle power" and then somehow chew through a stuck seat belt, then you are a better person that I am. For the rest of us, that is why they invented rescue tools. I do not pretend to be EMT, or a para-medic etc, but I don't expect professional help to arrive for at least 30 minutes depending where I am.
