I don’t think that is a good idea. It is pretty noisy already with all those a-holes honking for no particular reason and then imagine all of them using train horns. Small and annoying things like honking in a traffic jam like it will magically disappear when they honk. Or the moment the light turns green some idiot honks his horn behind you.
You must be banished from this community. The hornblasters bible clearly states that one must honk their horn(s) ANY TIME they see a great hornblasting opportunity or have due cause to do so under the highway code.
Guards!! Take this traitor away and off with his head!!
