I'm just sorry to see that in this thread personal insults and implied threats of informing employers occurs. Oh well.
Personally, I kind of see Nethalus' point -as it certainly looks like the cyclist was past the stop line. Assuming that is the case, then yes, I agree the cyclist pushed in front. However, being truthful, I most likely would also do something similar as it gives me the advantage of being easily seen, though note if I'd stopped behind the bus I'd still be easily seen by vehicles behind, and assuming I wouldn't be stupid enough to sneak up on the bus when it's turning I should be ok with the bus! (I can see this being a little of a questionable argument to me). More importantly for me though would be the size of the bus would obscure my view of the junction, potentially leaving me stranded in the box junction (which I wouldn't like).
A counter argument could easily be made that a cyclist should have simply waited behind the bus and not in the box junction, but realistically I wonder how many motorists would understand that(!). And as someone else pointed out, I wonder how many bus drivers have "pushed" their way into traffic? (quite rightly mind you in my opinion otherwise they'd be stationary) That's not to say it makes what the cyclist did OK or excuses it, merely that sometimes there has to be a little give and take and understanding of each different road user's difficulties to make the traffic flow easier and more efficient -for everyone.
So.... yes, count me as one cyclist who would probably do something similar (by the way, we don't know if the cyclist filtered with an intent to come into the lane *behind* the bus, but was unable to do so).
But also count me in as a person who recognizes that cyclists can do wrong, and that strictly speaking he was pushing in, however understandable and preferable it is from my perspective and personal opinion. However, I will say the comments on the video are over the top, particularly since the bus wasn't even held up!!
And lastly, Nethalus (and equally Magnatom), don't let the extreme detractors from either side get to you with personal invective and please don't rise to the bait.
