Hmmmm. I dunno. I paint alot of bikes, have my own, and know alot of bikers, riding in the city, cagers dont see or care about bikes, but when they hear them, you suddenly notice. Yeah there are some assholes thatll run thru 4 or 5 gears in a 2 block stretch, those guys suck and dont have alot of ride friends. But a set of ground pounders driving thru rush hour, atleast they notice, and pay attention. My truck is just as loud but I respect nieghbourhoods.
