You are doomed to disappointment, here's an example near to our hearts. We are still going to be bound by EU rules, due to the impossibility of unravelling the last 44 years. That's what Theresa May's inclusion bill is about, converting all the adopted EU laws into UK ones in a single swipe.And I think this whole move away from supra-nationalism is good - independent states figuring things out - rather than trying to impose global rules.
So we are stuck with the EU pedelec law and the EU type approval rules which ban throttles. Now add to that the fact that many components of the EU technical regulations are derived from and follow United Nations world wide regulations, for just one example, the way United Nations regulation UNC78 affects braking requirements.
You see we will continue to be bound by supra-national law, not just EU but world-wide law, it's the way things are.
And as the EU makes changes in their regulations in future, we will also be adopting those changes, since the inclusion law means the regulatory rules referred to in our ex EU laws specify the EU law as being the arbiter.
So we are in a "gotcha" situation, we may dream of independence, but it's illusory. We will still be very dependent and controlled from outside in many ways.
