Earlier quoted context omitted.

It's not remotely operated: > The GPS and sat phone work in tandem to provide the driver a detailed video screen image of the dozer’s location in relation to the center of the snow-buried highway. This driver’s job is not to clear snow, but simply to lay out an accurate track of the road itself.

Reading it again, I think you're right Makes me think though why could they not manoeuver it remotely with remote feedback if necessary, why put someone in the cab if they have it equipped with sensors. Some other heavy equip are operated remotely.

because if the terrain is dangerous to drive on (with all that snow, probably yes), the driver will likely judge much better than anything you could do remotely with current technology on whether to risk moving ahead or not

I would love to see that first bulldozer at work. I'm a little amazed because snow becomes incredibly heavy and hard to move/push when it's packed. As the blade moves forward, that dozer will quickly have to use incredible force to move forward. I experienced this first-hand last summer when I was driving my old Land Rover across the country. I was solo, way up in the very remote Henry Mountains [1] of Utah, about to…

Remember also that there's a big difference between the fluffy powder they're plowing in northern Japan and the wet stuff you drove your landie into.

The top may be fluffy, but by the time you've dug through the top 50ft I doubt it's very fluffy anymore.

We do have a few quite interesting mountaineous roads in Norway, too - matter of fact, a couple of minutes ago I heard on the radio that only two of the -hm, six? seven? I only ever use two of them- mountain crossings connecting eastern Norway to the rest of us were open due to lots of snow and poor weather in latter days. Those two are now convoy only. Have a look at this, for instance:(0) Not as elegant as the Japa…

Sorry slightly off topic. Crap! I think have crashed exactly by the Haukeli tunnel. It was years ago and we were doing a mountain crossing with convoy driving through the worst parts. I was behind some old geezer and just coming out of the tunnel he gets blinded by the light/snow and slams his breaks. Me too close and eager just behind him just somehow manage to overtake him in the narrow tunnel, but unfortunately had I too fast speed and bumped the next car slightly. There was just a small mark on the car, but they still did a full checkup and sent us the bill. My boss wasn't happy, but I didn't have to pay ,even if it was 100% my fault.The following mountain crossings since that I have taken bit more easily.

It's dense fluff...

There is a very wide range of snow. In particular, the heavy wet stuff acts and behaves very differently from "dry" snow -- whether that's light powder on top, or compacted, but dry, snow underneath.

Wet snow is increadibly heavy, and frequently contains or mixes with ice which makes removal (blowing, ploughing, shoveling, 'dozing) far more challenging.

Clearing doesn't always work. Here are photos from Hokkaido of cars with people in them buried in snow drifts.[1] Six deaths. One train derailment. Note the poles over the road with the downward pointing arrows. That shows where the road is, when it's buried. [1] http://www.dailymail.co.uk/news/article-2287894/Japan-storm-...
