Whenever I am cycling im always making the decision whether to cycle passively or in primary, there are certain roads within Bristol where I've had a previous close-encounter and therefore decided to cycle primary, in this case, this is another road where I will cycle primary, for me it is always down to the road it self, if i know it's not wide or theres a risk of someone overtaking me dangerously then I will obviously think about moving to primary. The reason why I did not cycle primary here is that it is already a narrow road (As you can see there are cars parked on the opposite side of the road) and I've cycled on this stretch with no issues at all, I've had cars overtake me there safely and I've had no problem, obviously with this case this is obviously different, the van driver no matter how much I was keeping up with traffic wanted to get in front of me. Riding primary here would, as someone has previously stated, probably cause the van to rev behind my self or even use his horn., I've had this on another stretch where I ride primary and had cars beeping their horns, it doesn't bother me, my priority is my safety, not how quick you get to wherever you want to go.
As for the camera use, I will of course use a camera on the journeys I make on my cycle, the reason as in this case is, evidence. Let me tell you, I've previously had a case where a hire van had previously turnt a corner in front of me cutting me up, I reported it to the hire company and they came back to me telling me the driver said that it didn't happen... thats where the evidence of the camera comes in, I was able to prove that it did happen. What if I had actually got hit by this van and hadn't had my camera, yes there may be witness's around but maybe not always accurate (people may not remember everything etc), but a camera would and therefore would be evidence available to use in court.
I said in the video 'Got you on camera', it was my reaction to what happened, having to evasively take action and brake hard like that because of his dangerous driving is of course going to p*ss me off and therefore that was my reaction at the time, I know some car drivers are the same when a car cuts them up....
