People will still be hobbyists with loud cars and motorcycles, though (at least in the US). We literally just need to legislate a package of laws that says people can't make loud noise with their vehicle, repeated offenses result in the vehicle being taken away, and anyone that modifies vehicles to make loud noise will be fined heavily.

I’m all for it it but unfortunately our local law enforcement in the bay couldn’t care less about enforcing existing noise violations for modded cars and motorcycles. So we can fill the books with laws but if they aren’t enforced it’s as if they don’t exist.
