Hmm... how do motorbikes (not hairdryers) approach this RAB?
Thinking to my approach to the traffic lights at Westminister, travelling out of the city along embankment, I ride down the LHS of the line of traffic and cut in one or two cars from the front so as to make the turn, starting in the correct lane in a visible, safe lane position. A little wave of thanks to the driver you cut in front of makes a difference.
last year when I was working in London and commuting every day, I was always as polite, smiley and wavey as I could be. I did this on the basis that as I always travelled at the same commuter time, it was reasonable for me to assume lots of the drivers I saw would do the same. After a few weeks I started to notice some regulars being more courteous, as they started to recognise me.
