I would probably be more inclined to use mine if it didn't sound like a freight train.
I wanted a set of locomotive horns for my truck till I found out what the damned things cost.
Same here.
I'll give a tap at a stop light maybe, but the real use of the horn is to pull alongside someone who's got a phone to their head and weaving all over, while not paying attention, and just lay on it until they hang up.
I'm just using it as a warning other drivers around the vehicle that's proceeding without an active driver, of course.
I smile and make a hang up symbol with one hand while I wait with the horn on. It's hard to have a business meeting from your car when someone in the lane next to you wont stop honking, I figure. Maybe you'll pull over next time.
(I don't care at all about hands free folks and non-weavers. This is definitely saved for the one that's going to just about jump out of their seat because they've completely forgotten that they are operating a frakking motor vehicle altogether and will be surprised back to reality.)
The other time Mr. Horn gets a workout is for left turners who run the red and then end up not clearing the intersection.
Again, just warning everyone to my right that there's an idiot still in the intersection. Heck, if I'm in the left lane with the truck, they might plow right into the idiot. Safety first!
And none of the above is ever needed pretty much anywhere but a couple of places in the city where it's epidemic.
The horn has one other use. Attempting to move deer, antelope, and other critters off or away from the roads near home. Sometimes they bolt, sometimes they bolt into the road, sometimes they just stand there like they didn't hear a thing.
The eight or nine point buck a few nights ago with his rack hanging over the edge of the road but his nose chewing the yummy grass right at the edge of the asphalt didn't seem to care.
