I have no problem on snow, and I even passed the superlicense ice course on the first try, but I am not quite sure of why.X-OthermicDriving on Snow is a SOB to master. I still can't do it.
I do seem to tap the accelerator a lot instead of steady press... maybe that has something to do with it. I also try to maintain steady control instead of going all out, and I don't even ride the walls any more. It feels slow but in the end the clock tells the story.
I hope that helps some. 💡
