while I was splitting nearly stopped traffic on 237 west. I was in the "+" where there were two cages to my front R & L, plus two more to my rear R & L. Not going fast, watching cages for unexpected behavior, moving through the traffic. To my surprise, a Buell appeared on my right, then snaked back in front of me, and headed on down the dots at a pretty high rate. first time that I've ever been lane-split while I was lane-splitting. when I notice that a rider is right on my tail, I signal and move over, waving them around. if they want to lane-split faster than I do, then I say let 'em go. the Buell made a nice 'parting of the sea' effect as he rode ahead of me. this also helped me as when he went by the cages, they woke up and looked in the mirror. when they see me coming also, many of them give way slightly. I'd like to give each cage who moves over 6" to make things easier a friendly wave, but I also like to keep my hands on the grips. Ken
