I live near Zurich and sadly the noise from luxury sports cars and motorcycles can be unbearably loud (even through noise isolated Windows and away from the street). I don't think anyone really enforces it.
Yeah, looking forward to it. People should have the freedom to move around wherever they want, but not to rob others from their quiet time and sleep in doing so.
Our street control systems are just getting started. Most people seem to have no idea whats to come.
