Manners please

i get undertaken by almost everything passing me, as i ride on the outside, its safer, and faster, generally.

I don't get undertaken or overtaken by anything less than 500cc :)

Same.
Speed and position will get you out of a lot of trouble if you are going quick enough.
You are less likely to be overtaken dangerously (in London) by buses and cars if you go a little quicker and stay away from the side.
