Zürich is testing "Lärmeblitzer"[1] which they want to put in certain places where people produce excessive noise with their vehicles. It will take time however as laws need to be changed to allow such devices to issue fines and they need to make sure the false positive rate is low enough.

Here in Germany, I'm convinced the Police simply don't care about motorcycles with modified mufflers. The sound is deafening. In the last decade the noise has gotten worse and worse.
Once one of those small penis motorcycle owners saw that I was covering my three year old child's ears as he passed by, and only then did he put his bike into neutral and walked it by us.
Germany has such a specific way of making laws with holes.
I really have no idea about all that. Just some absurdity I recently noticed.
And no, I don't have a loud motorcycle.
These, along with various other obnoxiously loud and/or big vehicles, are _strongly_ coded 'insecure man'. Not necessarily insecure about that in particular, of course, but insecure about something.
Aftermarket mods, revving your engine, or late shifting can net you a cool 5 figures fine.
Our street control systems are just getting started. Most people seem to have no idea whats to come.

However police is actively monitoring noise levels in some places, picking out the cars and remove them from the streets. Just last weekend my closest city checked 15 and removed about half of these cars in one evening.
