It was an interesting watch, but obviously was edited in such a way to cause controversy with the speccy guy and the vigilante, and that cab driver who was a kn*b and flatly denied any wrong doing whilst they showed him doing it wrong.
I think the problem lies on both sides. Drivers, imo, aren't educated enough on how to deal with cyclists, and I imagine very few realise quite how massive the consequences of their actions could be. I've experienced cars passing close enough to touch many times. All it would take is a momentary lack of concentration from either me or the driver and I'm under his wheels. I find it very strange how differently drivers react with horses and cyclists. Whenever I see horses on the road, people always slow right down, and crawl past leaving plenty of space, yet don't offer cyclists the same luxury even though they're more vulnerable...
Not that cyclists are any better. Those couriers deserve everything that comes to them riding that way. Perhaps that's why they all ride fixies and no helmets, so if they do crash they won't be able to slow down and it'll be a swift ending. They're does seem to be an unfortunate element of being 'holier than thou' with a lot of cyclists, which only pi*ses off more drivers
