I'd take it a step further and say the real story is that people are idiots. On a scale between Dangerously Oblivious and Zombie Apocalypse Prepper, most people heavily lean towards the former. Whether that's dressing for the conditions, driving for the conditions, keeping some basic emergency supplies in your car, having enough food in the house, having an emergency alternative heat source, etc. I'm not saying everyone needs a Unimog and a hardened bunker with a years worth of MREs in their backyard but, a little common sense and a little preparation can make most extreme winter weather nearly a non-event.
