This is specifically where I have an issue. This method of bicycle operation is FAR from courteous. It's disruptive to the normal and safe flow of traffic. Period.

I ride in any and all traffic lanes at certain times. But I employ a method of timing that allows me to get where I want to go by slotting in when traffic slows, so as not to impede it's natural pace. If traffic doesn't slow enough, I stop and wait for clean moment so that I can fluidly merge or cross lanes. You might ask, "Why should I have to stop or wait for a better moment? Why not employ the 'Control and Release' method?". My answer is, "Why is it OK for me to inconvenience dozens of other people for the sake of my convenience?"

If you need to cross two lanes to get to a left turn lane, why not work on improving your "Timing & Slotting" skills instead? Good "Timing & Slotting" skills are far safer and definitely more courteous.

There is also the elegance factor. Watching a highly skilled bicyclist employ the "Stealth & Blend" technique in heavy traffic is a thing of beauty. He safely navigates his route without disrupting the rush hour automobile ballet of chaos. He's out there, in it, but he isn't part of it. He uses all lanes, solo, elegant, fluid, clean, precise, stealth. His presence has no impact on his surroundings.

"Control and Release" is so clumsy that it borders on barbaric. It's as if finding a safe and elegant solution was too difficult, so barging, thrusting, and clogging became the tactics de jour. Those videos are difficult for me to watch. It's like a "How To" series being taught by Laurel and Hardy.
