That's a great find! And the best we can find are snowmobiles that get stuck and break down all the time. I couldn't get what it was called... thought Blacksheep first, but that was the OP's name on that thread. Any idea what it's called, as it didn't appear to be in the vid either.
That thing should be all over the Panhandle, not to mention the entire Midwest (except for the canyon roads and steep mountains, getting stranded on a highway would be a thing of the past). I can also see why it would cause trouble with trees, but as far as roads and barren planes, why are we still bothering with cars in the winter?
Now I too am curious why nobody can find one of those.

At least the engineering concept should have been applied to something smaller and more affordable, but I've seen nothing like that before.
