I like the idea of having requirements for sound engineering practices on vehicles that operate on public roads. While the people I used to race dirt track cars with were all there voluntarily and understood the risks involved, some of the rugged individualists here in the USA who insist on "doing it my way" haven't bothered to ask the soccer mom in her minivan full of kids if she minds being on the same road with something that goes like stink but can't stop or steer safely! On the other side of the coin, resisting the tendency of an all-powerful government to meddle in our daily lives is a big reason the USA exists at all. Good luck on your project, and keep us updated! It looks very good so far!
