Yeah, I think people who believe that pulling over is an easy solution may not have been in one of these situations. It can come up quickly and there may be no exit for miles. Pull over into what? The snow bank on the side of the road? Now you are a hazard for everyone else coming along behind you. Sometimes you just have to make it work as best you can until the circumstances change.
Again, I assume you've never experienced this. Storms can come up fast in the mountains and be very localized. As I, and the previous poster mentioned, it can be more dangerous to stop sometimes.
