I love bikes, used to ride in my college days. Now with wife and kids I can't justify the inherent risk involved with that pleasure
That said, I can't stand the loud bikes, the big throaty Harley bikes with the wanna be dork losers riding them. Nothing like sitting in traffic on the 15 and having one of these "rebels" go past my open window blipping the throttle. Loud = safety, my ass. Just wait till I get my full size commuter truck - oops gotta merge right, WHAM.
If you want to lane split (I would) then keep the noise to a freaking minimum and ride with some common sense. Yes I'm 40 for Pete's sake - what's that got to do with anything.
