No amount of safety gear, 4WD, traction control, snow tires, AWD, stability control....or anything else, will help a legitimate ****** driver who is trying to drive like a dry July day in a January snow storm.
I drove our old (Non AWD, and RWD at that) 300 through some hellish conditions with just good snow tires and it was sure footed, but I was also driving according to conditions.
Here's some photos of us arriving in Watertown a few years ago on our way home from a cruise. We drove through about 2 hours of near whiteout conditions between Syracuse and Watertown - reportedly they closed the interstate about 10 minutes after we passed through Syracuse due to the conditions. Watertown was a dream compared to what we had already went through though by that point.
Anyhow, like I said, AWD is great, 4WD is great, but so are a capable driver and good tires. Having driven the 300 through lots of crap I *still* wouldn't spec AWD knowing the fuel penalty it brings with it the other 99% of the year you don't need it.
