i didn't notice any - I'm no film reviewer so wasn't scutinising the vid. it's simply what I noticed.
I always look back - constantly - and judge the situation on it's merits as to whether to stay out wide or move in a little.
just describing what I do - not criticising the video. just sharing what I do. i set up for "cross traffic turns" early so as to avoid needing to fight across traffic, just not as early as the vid appears to depict.
And no, I didn't see any fighting across traffic in the vid - isn't it about avoiding having to do that too?
Its called "sharing the road". I'm not into all this critical mass "take over the road" crap. I sit out further than is "conventional thinking" so as to be seen/noticed, but I won't road hog. I'll pull in to make it easier for a car to pass, but still keep myself safe.
Take your too narrow lane: I'll not sit out in the middle of it. I will hold my ground in it, sure, but I'm not going to be a pain-in-the-ar$e to any passing motorist. It's just like corking.
Its Horses for courses and i'll make a judgement of safety vs courtesy as the moment warrants. This is by no means a concrete "do it this way everytime". Its possible to be both safe and not p*ss motorists off. The less angry motorists the better for all our safety...
The reason I like videos is because discussions about lane positioning are subject to so much misunderstanding, and I think some of that is going on here. Comments about specific scenes in the the video are probably less likely to be misunderstood.
First, I think critical mass in general, and corking in particular, does a terrible disservice to cyclists.
However, clearly, safely, courteously and legally controlling a narrow lane because safe within-lane passing is not possible is something completely different. Sure, if the adjacent lane is clear and it's safe and reasonable to temporarily move aside in order to allow for a straddle lane pass, I might indeed move aside. But I won't stay there because that leaves the impression that safely passing without encroaching on the adjacent lane is possible, and encourages close passes and other dangerous behavior.
Assertive lane positioning is not about being a pain or needlessly asserting our rights. It's about riding in a safe, legal and courteous manner. In this case, when motorists need to change lanes to pass, it's only courteous to help them be aware of this sooner rather than later, and there is no more effective way to broadcast this information sooner than via assertive lane positioning.
