As someone who uses Bristol roads on a regular basis and have been doing so for the past 30+ years. Driving motorcycles, cars, vans and trucks. I can tell you that it is the worst place I have driven in with regard to cyclists (yes I have driven in London in all but cars). Bristol has one of the largest cycle lane and seperate cycleway networks in UK, it also seems to have the worst cyclist attitude I know of. I quote a cyclist at my workplace when asked why he doesn't use the cyclepath on his route to work, "I do when I get to the lights so I can get through them on red, other than that their bumpy and my bike might get damaged" Millions of pounds spent so he can get round red lights, glad I no longer pay taxes to Bristol, so they can pander to tree huggers. None of this addresses the fact that he obstructed the free passage along a public highway which is also an offence. Try parking your motorcycle across a road to remonstrate with a driver who has cut you up and see what happens. Of course if you get a broken leg it's ok. At no point would nor have I condoned the bus drivers action, but the cyclist was not entirely blameless.
