I like the sounds of cars, and cars can absolutely have their sound tuned to be pleasant. Famously, Lexus for the LFA had Yamaha (yes the piano people) tune the sound of the engine and exhaust, which sounds absolutely lovely. Even far more mundane vehicles (not supercars) can sound quite nice. For instance, while I generally don't think positively about Ford, this last generation of Mustang GT had a wonderful exhaust note from the factory with the cutouts open, it was throaty and loud without being full of drone.
Nobody wants to hear an Aliexpress exhaust or the kid with the beater BMW leaking oil that they put a popcorn tune on.
Motorcycles are a different story, but motorcycle riders are also a different sort of asshole.
And sure, cars and planes are the best case scenario! Oh how I wish cars and planes would crash in great numbers into every asshole blasting vaguely music-adjacent crap at 1 AM in my area. That would make for a beautiful soundscape.
Seriously though, it's just very individual. Unfortunate people who are sensitive to noises can't ever prove to a person who isn't that it's a huge problem causing actual suffering.
It's all subjective. To me the idea of living in a city and hearing your pulse sounds like living in the rubber room of an asylum. Going to great lengths to do so is weird to me. I do however find the sound of engines and cars/planes pleasant so I'm probably lucky.
