Diane made an admittedly common mistake - confusing the definition of VC with the VC principle. That doing so misrepresents VC I'm not going to say. That doing so doesn't define VC is all I'm saying.
OK, and I have maintained here that there is NOTHING predictable about a cyclist riding into traffic lanes and then riding back out of the lane-- aka POWERWEAVE. nor is it in accordance with the rules of the road.
Whether you recognize it or not, the purpose of operating a vehicle in the traffic lanes is to be visible and predictable.
As far as the in and out thing goes, I assure that how often that actually happens is much more often in your mind than in reality, or in anything I intend to convey. Ask someone who has seen me ride, like Gene, if your impression even comes close to reality.
And to the extent that your impression does not match reality, the bulk of the fault is mind, for not explaining it sufficiently clearly. But no one can claim it's due to not trying!
