A video of those is making the rounds on Facebook. They actually float and can be driven on water also. Steer like a skid steer. Pretty awesome, but would probably be better as a tow vehicle than a full time driver.
That $65-70000 price might be a sticker for a few folks (unless that price is in Russian rubles which would be a little over $900 us dollars) if so I may order a couple. I'll bet those tires are a little pricey to replace. But that sure would be fun thing to have.
