I understand that 99% of 'rljing' is done in a perfectly safe manner, that is why very few cyclists get hurt or hurt others by doing it. But you are trying to make a reason as to why you should do it. You do not know how the vehicle behind you is going to act. You are just presuming that they might be a danger to you and that you would prefer to get out of the way. If that's the case then why don't you cycle on the pavement?
I was forced to go through the red light because a lorry behind me showed no signs of stopping. I'm not putting my self in harms where. The difference is you do not know if the vehicles behind you will run you of the road, where as i knew if i stopped, i would be flattened.
Personal judgement: I think that's absolutely key to safe cycling. Be aware of what is around you and make reasonable decisions on light of your judgements.
