Blood on the streets

How can you have a system where a HGV gets to a junction first, there maybe no asl but the presence of asl's in London leave cyclists believing they have the absolute right to always get to the front first irrespective of road conditions (e.g. light phasing, traffic density and lighting) and you really think that a hgv would or should just sit there and ignore the green light and sit there? The would be total chaos, and lead to frayed tempers and even more aggression on the roads.

Quite. It would be better if some inconsiderate HGV drivers paid a little more attention to their driving and obeyed the rules of the road. It would be better if some people on bikes took a little more care for their own safety and if they too obeyed the rules of the road. If both of these were done, the world would be a better, safer and less antagonistic place for us all. I see no inconsistency between the two.
