I had this great idea!
Automobiles really need two horns. Seriously.
The first would be all friendly-like. Like my current horn in my mini-van: Beep-beep! Meaning: Hi! It's me! Look over here and see me smiling and waving because I haven't seen you in a while!
And the other would be like the foghorn in our wagon: HHHOOOOONNNNNKKKKK!! Meaning: You're and idiot AND a moron, LEARN HOW TO DRIVE!
Something tells me I would be using the second one most of the time.
