the gospel according to Olly: Under taking
roll up the inside at the lights, slowly enough to drop anchor when someone opens a door on you, and with one eye on each wing mirror, one on each set of brake lights, one eye on the traffic lights for the queue you are in, one eye on the lights of the currently moving traffic (crossing the junction for instance), one eye on pedestrians, one eye looking out for other cyclists and mopeds.
IF youve got that covered, then you stand a good chance of survivial
if the lights flip before you get to the front of the queue, as the car in front of you moves off, but the car on your right pauses for a moment, take the space created and keep it, taking a central lane position, until you feel safe enough to choose to let the car behind you pass.
Keeping dominant control of the traffic with your road position works wonders.
i dont think i would ever undertake a lorry at the front of the queue myself, ide rather get behind it.
Home time!! (or at least time to slip off to the toilets to put on my riding home in the filth attire)
