Something like that happened last Winter somewhere in upstate NY. An older couple's car broke down later during the evening, little traffic, out of cellphone range, inadequate clothing, no flash lights, no idea how to deal with the situation. I don't remember if both of them or just one died by the time someone has found them. And we're not even talking here about great outdoors. This was couple of miles from towns. They just had no idea how to deal with such situation and didn't have adequate clothing. They could probably walk to a town if they could keep warm enough. They just hopelessly stayed put.

I see that behavior all the time: total trust for the car in bad weather. I always carry warm clothes in the car if I drive out of the city in Winter.
