I'm just not sure everyone around you should have to hear you enjoying yourself with the wind blowing through your hair or past your ears. Or have to listen to the music you're enjoying on your motorcycle on it's speakers, instead of through something like a Blue tooth connected headset with a Cardo Edge set of 40mm speakers in your helmet.
Of course, California is a weird Nanny state, requires you to wear a helmet, but one of the very, very few places in the world where lane splitting and lane filtering is legal, within reason.
I have my own beliefs.... I only will lane filter between cars completely stopped at a red light, for one reason and one reason only.... to avoid being squished or rear ended by some bimbo f*cking with their smart phone instead of driving, and not paying attention to the road or what is in front of them.
Usually soccer mom's where I live, with a 3 or 4 ton tank of a SUV, with screaming undisciplined bratty kids in back, distracting mom for driving. Being very serious about this stereotypical observation of mine.
Absolutely crazy today, now that kids are back in school and summer is over, how Mom's are driving around my neighborhood. Came, very, very close to hitting a Mom in a black Audi Q7 pulling away from the curb parked next to a school, without looking, doing an illegal U turn in front of me. ABS saved my bacon.
Spare me with loud pipes save lives. If that was so, they'd aim exhaust pipes forward, like the muzzle of a gun, to project noise forward, so that you can be heard by oncoming traffic. I rarely hear motorcycles with loud exhaust systems coming up behind me, but I can surely hear them a 1/4 to 1/2 mile away running straight pipes out the back, when running in front of me. No different than a muzzle report from a rifle or shotgun. The direction the gases are propelled, is the direction it's the loudest.
Listen to what a F-16 sounds like on takeoff, running down the runway, and then what it sounds like passing you by.
