I grew up in western SD and no one with a lick of sense drives around in the wide open spaces there in the winter without a survival kit of some kind in the vehicle. I reactivated my survival kit when I moved to MN to direct a program there a few years ago as it involved traveling around the state to 56 offices as far north as international falls.
That kit has air force surplus winter survival boots, heavy gloves and mittens, hand and foot warmers, a sleeping bag, a couple paint can (alcohol and toilet paper) stoves, an MSR feather light stove and fuel bottle, fire starting equipment, space blankets, a week's worth of MREs, a signal mirror, dye markers, a collapsible snow shovel, an aviation handheld radio and a roll of duct tape.
When appropriate I add a portable saw, 550 cord, a back packing tent, snow shoes, a water proof mil surplus flare case with about 500 rounds of .22 LR in it, a survival rifle - either an M6 or more likely a 9422 in a take down case - and the duffle gets swapped out for a soft frame backpack.

That same kit goes in the back of my Citabria or Pacer if I am flying anywhere where I couldn't walk to the nearest habitation in a very short time and or where a crash or forced landing migh not be noticed.
I also have a full trauma kit in each aircraft plus another in my truck.

The closest I've come to needing a survival kit was on a back country cross country ski trip where we were 11 miles from the nearest habitation or shelter in about 4 ft of powder with deteriorating weather when my wife broke one of her ski bindings.
We swapped skis and I used duct tape to keep the broken binding ski on my boot and we skied out. Option two would have been using the back up snow shoes to walk out. However that would have also involved staying out over night in the worsening weather.
