I think the van driver's intentions are good. Only thing I disagree with him is the way he pulled alongside the riders. Unfortunately where I live a lot of riders are nowhere near as passive as these and unlike the author would never accept they were in the wrong. Takes a big man to admit he was wrong and the rider did just that.
Quote the up-loader: "I accept that this was my fault and I acted aggressively, I accept that. And I know that I shouldn't have pulled out and I regret having done so. It was stupid to have pulled out at that time and I probably could have been a little less aggressive during the encounter."
For once a white van driver is justified at mouthing off. I hate these gangs of pimply pricks on their pathetic little buzzing machines with malodorous emissions and permanent L plates driving like lemmings.
Camera car is following far too close here; Audi driver could have pull over to let this idiot past, brake checking is never a good idea.
