Perhaps the Americans you are referring to were used to running roughshod over everyone and everything but that ship has sailed here. Unfortunately for you they can continue to do so there...Perhaps Americans being so use to riding rough shot over anything they don't agree with, can do the same in the UK. So far it seems they can.
They no outcry from the public or press/media for points deduction etc for bringing illegal rules. In fact it's the opposite blaming City for challenging the illegal rules !
