Yes I Gnow that but I sure wouldn't want to drive one on a slippery slope. When I was on my Scorpion light tank drivers course we stopped for a brew of tea. We stopped in the middle of an open clay area so we could fire up the chuffer. As we were standing beside the vehicles waiting for the water to boil we suddenly realised one was slowly sliding away with the tracks completely locked. The vehicle in question had a set of tracks that were worn almost smooth and were due to be replaced a few days later. The clay pan was damp and had a very slight slope - gravity took over
