I am hugely surprised after all the incidents between these two, Mercedes have not educated their drivers on appropriate attack and defence techniques. Surely this has been discussed to death in their boardroom?

I am also surprised fans on an f1 forum appear to have a better grasp of the rules and driving standards than a current driver. Nico either doesn't know, or he's playing dumb in front of the media in the hope the stewards will give him the benefit of the doubt.
