In reply to shaymarriott:
Apologies for the second paragraph - as you may have worked out I meant visibility was approximately 50 metres left, not right.
I'm glad I didn't hit him for insurance purposes (and for the obvious reason as well) as it would probably be a nightmare to sort.
He almost certainly wasn't breaking the speed limit, but I would say that he certainly wasn't riding to the conditions either. Overtaking at a junction is potentially lethal, and although there was no oncoming traffic he clearly didn't expect someone to pull out.
For the record, regardless of what the HC may say, to me (and any drivers I know who you might like to ask) flashing your lights at someone is an invitation to advance in a situation where you might not have the right of way. However, for a cyclist who was to far back to see the buses headlights they might as well have just left me a gap. From their PoV its irrelevant. However, they clearly didn't observe the bus enough to notice that it had left me a gap.
I once heard someone say with regard to motorbiking in heavy traffic that you should never move more than 10 miles an hour faster than the speed of the traffic, as this should give you enough to time maneuver evasively in the event that you might need to.
Anyway, thanks for the responses so far. I'm glad I didn't hit him. As I said before I have great respect for cyclists, although this goes straight out the window for those who jump red lights, cycle at speed on the pavement, and think that they're above the rules of the road.
@Rigid Raider - get off your high horse - have you never accepted a flash as an invitation? If not it must take you bloody ages to get anywhere. Thanks to GrahamD for your response!
@Ramblin dave - when pulling out in normal road conditions (no traffic) you have to check right (you can see far enough to know you're clear) and the pull out into this lane so you can see left. I had checked right, and from the left the bus had allowed me to turn. I imagine that many people would just assume that meant a clear road and would then pull out normally, but fortunately I kept an eye out left - this is what stopped me hitting the cyclist.
Obviously I'm not a bike-hatin' white van driver or someone who wants revenge for the behaviour of this two wheeled hooligan - it was an error in his judgement, and an error in mine, and in this case it was mostly my reaction that stopped an accident in which he would have come off far worse. I wonder how many accidents do happen from cyclists overtaking on a road where overtaking in a car would be unthinkable?
