Air horn

[MAC]

Stupid question maybe, but I could not help wonder: wouldn't it be rude to use such a loud horn? The H2 horn sounded weak at first, but not bad if you hear it from outside or open the window. I rarely honk, if I do, I rather it not be too loud, I just want it to get the #@$%^%*& out of my way, please. The preconceived notion about a Hummer driver is already arrogant, rude and self-centered, add that loud air horn would certainly confirmed the misunderstanding. Wouldn't people think it is rude? it is sort of like a huge boombox blasting rap music on the street or bus. Or being rude is not a problem but actually a statement you want to make?
Hummer is already the strongest possible statement you can make, why do you need to blast an air horn? Am I missing something here?
