I do 100 miles a day round trip on the toll road. So if conditions allow I set the cruse to 74. If there's any snow on the ground in weary of ice and keep it at 50 or less. You can go pretty much as fast as you want in a straight line in just snow, but you can't really see where's there's ice, so it's a pretty bad idea. Wednesday morning there were severe white out conditions and I though I was going to die. I was going about 15 at times when the speed limit was 70. Everything after that hasn't been a big deal
For the most part the zhp does really well. Snow tires are a must, and getting going (or stopping, more importantly) can be a challenge on slick ice. The only other problem really is bottoming out. And that's pretty rare on roads that are plowed every once in a while. Just have to take everything slowly and make very gradual changes in velocity or direction.
Unless of course you find a deserted parking lot... Those snow donuts aren't gonna do themselves!
