Thanks for posting that!
The guidelines seem pretty sensible. The only one I hadn't thought about was not lane splitting between the two slowest lanes because of cars entering/exiting the roadway. That makes sense too, and I'll keep that in mind.
I am a little concerned that they are tasking UC Berkeley with the study. They could very well decide that we must have flowers painted on our bikes to be legal when lane splitting, or that lane splitting hurts someone's feelings or exposes drivers to exhaust noise, and should be outlawed. Seriously.
