A great, fast ride in this morning (living the school hols!), very nearly ruined by a grandstand view of a cyclist-meets-van collision. Thankfully contact was -just - avoided. I was riding along behind a slow-moving van which was dithering appriaching a junction. Road ahead was closed, so it was obvious to me the van would turn left at the junction, even though it wasn't indicating. Whereupon a cyclist comes flying past me, dives into the cycle lane on the left to pass the van, which promptly indicates left and starts turning. Cue cyclist emergency stop and much swearing. Yes, the van driver was at fault, but really, the cyclist didn't help himself there. I'm not sure he appreciated my suggestion he read the road better in future. (Incidentally, the van subsequently turned right at the next junction without indicating at all, so clearly not the best driver!)
