yup it's legal in california.

Sure is... my buddys trip out when they visit from out of state

It's not legal here in Florida, however we can essentially get away with it if we do not endanger anyone and can maintain a "safe" operating speed.

But yes, I'd get pretty pissed if they blew by me at 60 lane-splitting

ya thats what pisses me off lol. if they roll through at like 35 mph idc more power to them

ooo i did it when they werent moving, queued at a long light. I rarely find the need to do it while moving so i only do it every once in awhile
