in defence of the driver, there may have been a 40 tonne truck coming towards him at 100kph.
as it looks like that there is quite alot of traffic backed up behind him, because he has already had to slow for this self righteous wanker on the road bike, he is not in a position to brake to allow some space and wait for a safe spot in which to pass, for fear of being rear-ended by a procession of following vehicles
If it was a contest between hitting a 40T truck head-on or a close pass to a road cyclist, bike looses!
given the same situation, I would have done the same...if we had wider roads, not a problem...but we don't!
P.S. why does the cyclist have to be so far out into the lane anyway?
