I live in a neighborhood that just about everyone has a bike with loud exhausts. it is accepted.
I expect this sentiment is echoed by several of the "Loud Bike Crowd", so don't take the following as a personal attack.
I believe the statement that "It is accepted" is a misinterpretation.
They may have simply decided that the noise being made wasn't worth the effort of hurling a brick at the perpetrator. Or, eliminating the problem at its source. They also know that calling the police will, at best, bring a patrol car 15-30 minutes after the event has past, and then only if there isn't something else to do or they feel inclined to do more paperwork.
Even if you actually have a neighborhood where each and every individual "accepted" bike noise, do you only operate your bike in that neighborhood? I venture to predict that other neighborhoods you ride through find people who are not so sympathetic to loud pipes. Do you care? If not, this would explain noise ordinances and their proliferation.
I have noisy bikes in this neighborhood, as well, along with the boom cars that try to make up for the small engine size and low IQ levels with festival levels of speaker emanations.
It is not accepted, it is forced upon me and my family.
Infants and children always push the boundaries of behavior in order to establish just where those boundaries are. Some people don't mature beyond this practice. If Joe cool has a loud bike, then I'll make mine louder to be "cooler". Besides, who's going to stop me?
Well, it is communities that have had enough of infantile behavior, that will stop you, or make you pay dearly for it. Infants and children also complain loudly when limits are imposed.
Usually, if you slap someone in the face (or ears) often enough, something will be done to get you to stop. Can someone that doesn't deserve punishment be hurt, too? You betcha. Especially with an over-reaction. However, if you loud pipes guys won't police yourselves, why do you not expect an abused society won't do it for you?
Your freedom to persue happiness does not extend to my ears. I love the sound of a well tuned engine singing the horsepower song... at the track. But, not when I'm trying to sleep through the flu or cope with other illness, hear a quiet passage of music or movie, have a discussion with a family member, have a phone conversation, or simply relax after a long day in a noisy, hectic environment. Your noise intrusion is a personal attack. It is NOT accepted, even if it is tolerated on occasion.
Do I pay for your adolescent persuit to be noisy on a bike? Yes, I do. With extra animosity from drivers at anything on two wheels. Is THAT fair? Do you like being a willing accomplice to other bikers injuries?
You want to save lives? Stop antagonizing the populace, be they bikers or not. It is a problem within your control to do something about. How many excuses will you use to avoid taking appropriate action?
