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.<p>To be clear though I don&#x27;t think that&#x27;s the reason loudness isn&#x27;t enforced. I imagine it more has to do with the fact that they aren&#x27;t watching for it since they don&#x27;t have any way to easily test it like speed.
