By no means am I trying to say that excess noise is good, nor necessary.....but rather I don't think the real issue....in most cases....is the noise.
There are the tree hugger groups that just do not want bikes on public property.....period. They say the bikes destroy the natural enviroment. I think it is EASIER for them to get the bikes banned on the loud noise, than it is on the destruction of the enviroment BS.
As a general rule, the noise level from todays bike (even the modified ones) is less (overall), than it was 20 years ago......yet the uproar over the noise level continues. I do not think it will ever go away, regardless if ALL bikes are below the 96 db level.
PAC is what is needed. It will take a stronger political lobby.......IMHO.
