as someone who lives not too far from magnatom and cycles a lot of the same roads, particularly the recent 'taxi driver roundabout exit' I have to say that, whether intentional or not, I do believe that Mags takes an unnecessary primary/weak primary road position far too often and, as a result, experiences a lot more incidents than your average cyclist would. Coming off that roundabout there is plenty of room for a car to safely pass in the approach to the pinch point and mags had pulled across the road unnecessarily early.
I'm by no means a gutter hugger when it comes to road position, but we all have to remember that we are slow moving traffic at times and don't have an undeniable right to hold up other road users unless we believe it would be unsafe to act in any other way.
I'd also add that he comes across as far too aggressive with certain road users. Not the taxi driver maybe when i'm sure he was in shock, but the lady driver who was about to reverse into him in a recent clip was obviously apologetic and shocked at what she'd almost done, but still had to sit in her car while an angry looking man shouted at her through her window. Incidents like that one could be good lessons for drivers,but if the cyclist over-reacts it's more likely to simply increase antagonism towards cyclists.
So, I reckon he should give up the cam. Subconsciously I think it does alter his behaviour as he believes it's a safety net which leads to an unnecessarily aggressive cycling style and over-the-top reaction to incidents.
Actually, if there was no cam there'd be no "have you read cyclecraft?!" clip which i saw for the first time yesterday. cam must stay!
I'm still quite new here and could be totally wrong though.
