Even more interesting, why do you think females dont show the same behaviour, generally speaking?
Women DO show the same behavior, when it is necessary. For instance, in this case if the husband had been sick or injured, perhaps he would have stayed with the car and kids, and she would have been the one to go for help, if they decided that leaving was the only option.
If it had been only the two of them, with no children involved, I think they would have stayed together, whether they decided to stay in the car together or leave together.
All I know is that it was a bad decision for him to leave. The family needed the extra warmth that his body could provide by staying in the car.
One other thing that I am wondering: This guy was a very high-tech person, being the senior editor of a tech magazine. So I would think he would have a car equipped with that Garmin computer/gps thing that tells you where and when to turn to get to your programmed destination.
However, even if the car DID have such a thing, I am wondering whether it would have worked in the wilderness area where they were, since they were off the beaten path and on unmarked roads.
And don't they have some way of installing some kind of chip in all cars these days so if you get lost, you can be found via satellite or something? Or to find your car if it is stolen or if you get carjacked or kidnaped in your own car etc.?
When Rick and I were living in Vail, Colorado for several years, our car was always stocked with blankets, water and some food, matches, a Swiss Army Knife, and some tools, in case we got stranded somewhere, because you never knew when the unexpected might happen.
The problem is tourists and people just passing through, who are not aware of the potential dangers of the area.
