Vision is one problem under snow and ice. But the one I think will be tough to overcome is operational. In normal conditions, your car stops in a predictable way, at predictable speeds. It doesn't slide. It doesn't follow cut-paths in the road. Acceleration is a simple function. Think that you've adjusted for these parameters? Well, the ground you've driven to has more snow on it then before. Or you're elevation has decreased so the snow:ice ratio has shifted towards the later. And the above only describes the situation if you are one of the few people on the road. Add in all the other drivers who are acting _strangely_ in terms of performance and psychology. Driving lanes shift depending on where the road is clear, typically centering (bringing sliding cars closer together).
