It was entirely his fault.
*I use the term cyclist loosely, it was a chav on a supermarket special (no lights/helmet/hi-vis) but to the general public, he's as much a cyclist as Steve Peat or Bradley Wiggins.
Driving out through the salubrious delights of Droylsden, East Manchester about 5pm - it's getting dark, about 1 deg C, light sleet and I pulled up to the rear of an arcticulated lorry in a 2-lane section. Cyclist pulls up to left rear of lorry; initially I thought he was going to go up the inside but no.
We moved away from the lights and dickhead was holding onto the back of the lorry as we crossed the junction and the road went down to 1 lane. I was one car back from the lorry. Next thing, the road does a right-left jink where the new tram stop is and crosses the tram lines (which are of course soaking wet). I could see what was going to happen, it was obvious and sure enough, the back of the lorry swung left as the driver went right and the insweep of the kerb slammed the guy into the back of the truck and he fell off. He was OK - picked himself up and was sorting the bike out by the time I passed. There was too much traffic for me to stop but the lorry pulled in ahead so I guess the driver had seen him. Hopefully got out and gave him a good kicking.
And you wonder why cyclists get such bad press...
