Advice to Cyclists
Those pretty red lights you sometimes get at junctions are an instruction that you should stop. As in, not pass them. Cease forward motion.
If you don't stop, then you are liable to meet me as I am crossing the road on foot. You really don't want to do that. The lycra-lout who nearly ran into me today as I was out getting my lunch realised that he didn't want to run into me, and fell off his bike at high speed trying to go around me. I speak from personal experience that road-rash hurts, which in this case is a Very Good Thing. Also, the tinkling sounds from his bag sounded pleasingly expensive.
