I tend to agree, but I am also convinced that pulsing lights are incredibly annoying and create more ill-will toward splitting motorcycles than good. It is also my understanding that riding with pulsing lights/hazards is also illegal unless you're indicating a traffic hazard.
The vast majority of cagers are not in the way of a splitting moto. For those that are, a quick flash of your high beams should be all it takes. As others have noted, cars are not obligated to get out of your way.
Motorcycles are allowed to modulate their high/low beam headlight under CVC, at a rate of no more than 180 flashes per minute.
My Burgman 650 with the modulated headlight gets the split lane to open like Moses and the Red Sea, whereas my other bikes get much less favorable treatment. I don't consider it rude- I'll use any tactic I can to increase my likelihood of being observed.
