I drive the mighty Cascade Mountain Passes all of the time .
I use studded snow tires mounted on separate wheels for winter usage .
I live at 4100 feet ASL and I am about 450 feet above the city so I have snow in wintertime when the town can be down to bare pavement .
I am also in a sportscar club and we do some skid pad events on wet pavement .
Experience counts when " drifting " .
What I have discovered from 4 decades of this kind of winter environment is that there is no substitute for 4WD ( or AWD ) and fresh winter tires , especially studded tires .
I can and do drive faster than much of the traffic in the passes that is populated by the city folk who live at 300 feet ASL and do not have the equipment or experience that folks from 3600 feet ASL have .
I carry a nylon tow strap and I have pulled a few out of a snow bank when my trip is not urgent .
I will say that my 4wd diesel truck with the 400 extra pounds ( diesel engine ) on the front wheels is the best snow vehicle I have had in 50 years of driving .
In a 2 WD truck the extra weight in front is not an advantage .
The rear end is too light if the truck is unloaded .
