Last Saturday, I got to see a car fly off the highway, doing a 180 in fresh powder. He started to lose control as he approached us in the oncoming lane, and then swung around behind us. We went back to check on him, and I was surprised that no one else stopped. The thing was, he was at the bottom of the embankment, and the 6' high weeds had totally swallowed the car. Or maybe the others passers-by just thought he got what he deserved.
Sorry, though, it was not an SUV, and did not "turtle." Just a young guy without much sense.
