I'm sorry you silly biker but if you insist on riding in the 'dominant' postion (i.e. one third out from the kerb) as you smugly call it, don't whinge when I use the remaining gap between you and the centre white line to overtake you. No way are you going to force me over that white line and possibly into the path of oncoming traffic just because you have some chip-on-your shoulder about motorists in their nice cars, a character weakness or are just bitter at being one of lifes losers. Ditto the bikers who insist on riding side by side on a busy road - ah! bless they need to keep each other company and of course revel in holding others up.
