Not only does the sound from bikes not reduce traffic violence, the sound itself causes immense amounts of measurable and real harm in the form of noise pollution. Many studies are confirming that noise pollution causes way more damage to the health of human beings than we realized. Obviously, some things in the world are necessarily loud, like a jet engine on a plane. Or they are loud with a meaningful purpose, like a big sound system at a concert. But some things are unnecessarily loud with no purpose. Mostly vehicles with modified exhaust and sound systems, but also some other things. If the noise pollution studies are accurate, reducing or eliminating these sounds will extends the lives of untold numbers of people. People will be healthier thanks to getting better sleep not being woken up. People will have lower blood pressure, and therefore reduce heart disease. People will have less road rage, which will in turn reduce traffic violence. How do we actually reduce these sounds? Our current policies are not working. Fining people, impounding vehicles, I don't believe any of that will work. It will simply create revenues for the government. But what solutions does our current society offer that will work? The criminal justice system is not a solution, and will simply cause even more harms. Any solution I can think of that will work is ludicrous and unrealistic. The best thing I can think of is to simply ban the import or manufacture of the exhaust pipes to begin with. If the supply of them is greatly reduced, and the prices go way up, that could go a long way. It's too much to enforce any restriction one by one. It has to be from the top.
