Not sure what you mean by 'filtering' - it looks like overtaking to me, but what I mean is where you are going past moving traffic. I don't know what the h. code says, but in that situation I would not overtake where the cars are moving, I think you should be moving 'in lane' with the traffic. I don't know if you drive a car, but I would find it pretty scary to have you appear from nowhere, flashing by inches away. I watched a few of your vids, and while you have some serious grievances, you don't seem to show the level of consideration for other road users that you demand from them. eg the bus driver - nasty overtake, but not so different from your 'filtering'. Would it really have hurt you to move over into the cycle lane and let the driver pass safely? Can't condone him overtaking like that, but I'm not surprised he told you where to go. When you get a chance to remonstrate with them, you shout incoherently, which achieves nothing, rather than talking, explain why you are so upset, and possibly educate them, and possibly yourself in the process. I felt quite sorry for the woman by the end of the incident, I wonder what her attitude to cyclists is now. I hope I'm not confusing your vids with someone else's, but the contrast between your reactions and the behaviour of the car driver that you inexplicably crash into (playing with your camera perhaps?), is quite stark. If it had been the other way round, what would you have done?
Sorry to be so negative, but keep on with the vids. I thought "c'mon...get a life", but it's great to have hard evidence of what cyclists face everyday, and some drivers deserve to be on youtube, numberplate and all, preferably with points on their licence. That bendy bus is terrifying. Fortunately buses are a rare sight in these parts.
