The police on High St Kensington

That's never how to do it.

What you need to do is respect their authority.

Just repeat after me: "Yes officer, I know I was in the wrong, I jumped the lights out of an abundance of caution for my own safety when the lights change but I realise that this is against the law and not a smart idea, thank you for setting me straight. I will stop at the lights next time, of course I will officer. My, what a large night stick you have.".

Basically, keep your mouth shut and suck up to them and be all puppy eyed and guilty... they may let you just ride off with a good telling off.

I'm talking once they have fined you. Before you reach the point of no return it should definitely be as above, maybe slip in a compliment "why officer, your ergonomic safety shit kickers make you look so handsome and commanding".
