Tshelfer kind of says it all when he called this "a new trick for the toolbox"; like all riding techniques it has it's place and applications, but I'm a big advocate for "riding according to the situation"; the situation is fluid and techniques that save you in one incident can kill you in a different one. In congested urban riding I float all over the lane depending on the proximity of the cars around me. I also tend to ride slightly faster than prevailing traffic so that I'm overtaking cars slowly; that way everything is out in front of me, traveling a few MPH slower than me, and I don't have to scan the mirrors quite so frequently. Lepers, due to the nature of their illness, have to practice what they call "VSE" (visual surveillance of extremities), wherein they continually examine their extremities because they can't feel any injury or bump, and bruises or cuts when you have leprosy cause infections, gangrene and amputations (gruesome, I know, but riding can have those same results). So I have my own version of VSE where I continually scan all conditions around me using all my periphereal vision and including the mirrors in the scan. Staying safe around cages is generally all about some degree of separation. I call this "separation anxiety" because I'm anxious to stay as separate as possible. So, for me, the memes are "float like a butterfly, practice your VSE, and maintain a high level of separation anxiety".
