In going on eight years, the only time I have ever honked the horn was to get somebody to hurry up and come outside to go somewhere. If I want to get someone's attention in traffic, for whatever reason, I have been known to "blip" the throttle. You can do it in such a way that the engine doesn't really rev, rather it explodes in one quick blast. It's more effective than a horn, unless the person you're honking at is in the bathroom....
