A few years ago when we had the beast from the east, I was driving through a village in my van, the road was covered in hard packed frozen snow when a black range rover sport came towards me completely missed a slight bend in the road and went down a small bank and ended up in a front garden. I stopped and the driver was a woman early 30s she was ok. She said she couldn't understand what happened as it's a 4x4 and should be fine in those conditions. I said all the 4x4 bit does is get you in trouble quicker but I don't think she understood.
