You only ever hear about people who run away from cops badly. Motorcycles are usually long gone before the police have a chance to call a helicopter, which they would be able to outrun anyways if they were on a straight road.
To be clear though I don't think that's the reason loudness isn't enforced. I imagine it more has to do with the fact that they aren't watching for it since they don't have any way to easily test it like speed.
Said by those that never try, and by cops that believe their own macho BS. Though often successful, I highly discouraged it, because it's very dangerous for yourself and endangers others as well. Additionally, make a habit of it and you'll eventually get caught and enjoy free accommodations courtesy of whatever county you're in at the time.
If they have a video with a license plate record of them running away from police, then why don't they revoke the plate and impound the vehicle at the registered address?
I, too, would love to know the answer to that question. I've been seeing them all over in NY, where I understand they're illegal, and have no idea how they're not cop magnets.
Back in the day, I lived on a dirt road, and I never washed my car. So the tag was a little hard to read. But hey, there was nothing obviously intentional about it.
