The earlier post about the vehicles down south aren't equiped for winter driving (no 4 X 4) reminds me of what a guy told me 50 years ago during an Iowa winter.
"A 4WD will just get you into the accident at a higher speed."
The brakes don't work a darned bit better on ice.
I also learned the hard way to drive into the mess in 2WD and then BACK OUT in 4WD. If you go in in 4WD you are usually really stuck and will need a wrecker!
Best lesson, if the weather is predicted to be bad, be it ice, snow, or a hurricane, STAY HOME.
