Big statement Dan, so hundreds of Governments and people around the world have got it wrong !
More grip on cold compacted snow/ice? No chance, you cannae break the laws of physics Jim.
Go and get a brick and slide it on an icy pond.
Then get another brick and place it on 400 grit sand paper and slide it on the icy pond.
Then get another brick and place it on 60 grit sand paper and slide it on the icy pond.
If they all slide to the same point at the same speed. Then I'll believe your version of physics.
