Even though you don't like to hear it, and to some extent demonstrate a certain state of denial towards it, the fact is that CM and other YouTube warriors have created a large amount of antagonism towards cyclists.
I was at a real world meeting last week, a public meeting open to all, in a town with a population of over 100,000, and I was almost afraid to admit that I rode a bike such was the animosity towards people on two wheels, most of that animosity being fuelled by a perception that cyclists do not care about other road and pavement users, consider themselves above the law and go around with camera's shoving the law down other peoples throats. "Youtube tw*ts" or similar was the most used phraseology.
CM's main contribution to road safety are the bits of video evidence he sends to Met police online, not the YouTube video's he posts. They just fuel that antagonism towards cyclists, as was clearly demonstrated at that meeting.
Really, what a shameful state to be in where anyone indulging in one of the healthiest and most pleasurable recreations on the planet are treated as some form of two-wheeled vermin by a large number of people. Correcting that state should be a priority, kicking people off bikes that ride on footpaths, confiscating bikes that do not display lights at night, kicking people off that go too fast and pass too close to others using shared use spaces .... etc.
When cyclists as a whole demonstrate a respect for the law then road users as a whole might demonstrate a respect for cyclists.
