Manners please

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.

Yep. I don't ride in the gutter for no one. I ride like a muppet some times (everyone does) but generally keep myself out there and visible and don't get intimidated by wankers laying on the horn or whatever. Riding 'with room to move' also means you have more chance of avoiding cunts that snap change lanes without indicating.
