There was once a cyclist I didn't see in time. I was driving in town on a wet December night and had stopped in a queue of traffic, which a cyclist overtook. When I moved off, he was almost alongside me and a little bit too close.

I can't say he wasn't showing lights, in fact the front of the cycle was festooned in them, of all colours - white, red, green, amber - the lot. Normally he would have been well visible, but at this time of year his display formed a perfect camouflage against the background of Xmas shop windows. So despite checking my mirror before I moved - and I did check - I didn't see him and almost knocked him over. Fortunately, only almost.

Sorry, I drift.
