Sounds like confirmation bias. I don’t know if there is a higher noise ceiling than cars. I’ve seen plenty of people in cars rev their engines. And it’s wildly common all over the USA... Civics with fart pipes, trucks rolling coal, v8s with a muffler delete, etc.
Most motorcycles are built with an enthusiast in mind who wants a louder bike. Most cars aren’t build with enthusiasts in mind.
I’d love to know why we’ve allowed delivery vehicles and buses (commercial vehicles) to have similar noise regulations. Since those vehicles are really only for utility, one would assume we’d regulate those into quietness at least...
I would have assumed the opposite. For delivery vehicles and buses, there is a much larger payload, so there is a higher burden in maintaining the same volume of engine. For a personal vehicle, there is little excuse for having a loud engine. Then again, my apartment is adjacent to a busy 4-lane road, and so my opinions may be colored by the motorcycles and sports cars that drive along it every Friday night.
