I can only think of THREE valid, legitimate uses of a car horn (and there are other valid actions available for each) - if you're stopped at a light and you want to alert the car in front of you that he's drifting back towards you. Or you've driven into a ravine and you're signaling rescurers where you are. Or you're coming down a hill and you're warning others that you have lost your brakes. And even those happen so infrequently that I think manufacturers could just eliminate the horn altogether and save a few hundred dollars per car.
Every other use of the horn is simply to call attention to how self-important and obnoxious the driver is, e.g., "How DARE you try to come into MY lane!"; "I'm in your driveway, don't expect me to get out and come and knock on your door."; "HEY! The light''s been green for 3 seconds and I've got things to do!" "Don't you dare step into that crosswalk, I don't want to wear out my brakes stopping for you!"; "Hey fool, get out of my way. The speed limit's 45; that means I can go 55.",
Or to let you know that something happened or is about to happen that neither you nor I can do anything about now, e.g., "You pulled out in front of me and I'm going too fast to avoid you so I'm going to hit you."; "You idiot, you just cut me off!"; "This back-up must be a mile long. Maybe blowing my horn will get it moving."
Then there's the simply obnoxious announcement that something happened that nobody, other than you, cares a whit about - "I just graduated from high school."; "We just got married."; "My favorite ball team just won a game."
