Whiteouts is of a true a cool but dangerous natural phenomenon, getting lost in that, won't wish that for anyone, now imagine a pilot experiencing such when on a plane, that is disaster calling.
With modern navigation systems one is reasonably safe.
I have never experienced whiteouts, but I've experienced getting lost in the mountains due to blizzards. The compass did not agree at all with my "internal" compass - I can't remember if I decided to believe it was a problem with the compass or not. Of course the compass was right and I was wrong. (This was before the age of GPS and smartphones).
I would believe blizzards are a lot more dangerous than whiteouts.
Blizzard is quite A dangerous natural disaster which have caused a lot of havoc with the snow, won't wish such on anyone too.
Disastrous occurrence sometimes just happens, we should just get prepared for them when they come, for more on disasters, you can visit @whileponderin, I think he did something on Blizzard sometime ago.
Driving in blizzard conditions can also be quite dangerous. In the worst case one can get stuck - then it may be important to carry some drinking water, snacks and blankets in the car. (Driving in extreme temperatures as well ... ordinary "winter diesel" has a minimum temperature. My wife was once hitch hiking in -50C from Murmansk to Kirkenes). I've never experienced such conditions, but I've experienced trying to drive when it's impossible to see anything but some few metres ahead of the car, as well as impossible to see the edges of the road, in such conditions one has no option except driving really, really slowly.
