There is a specific kind of "winter morning" feeling we all know too well. You’re bundled up, the coffee is hot in your cup, and you walk outside only to find your car encased in a thick shell of frost or buried under a fresh layer of snow. We’ve all felt that temptation: you clear a tiny "porthole" in the ice just big enough to see the road directly in front of you, blast the defroster, and hope for the best as you pull out of the driveway.
