Doesn't it? AFAIK it's illegal to have a noisy muffler, at least here (but it's not enforced, much to people's dismay).

Assholes and annoying people will find a way to skirt regulations.

The more pressing thing is that if you keep asking for a big brother, don’t be surprised when you get one.

Such a weird dichotomic view can only come from someone who’s never lived in Europe. Loud cars and motorbikes weren’t a thing in Germany, where I lived for 30 years, and yet I had the impression that my privacy was also much better protected and respected than here in the US.

Giving hefty fines, or even outright confiscate veichles, to people blatantly ignoring the law and infringing on other people's well being. That's not "big brother", that is trivial to accomplish with a well-organised vehicle inspection programme.
