OT: Honk if you... honk

I found an article about the alleged need for the car horn that talked about how it has little to no impact in preventing road disasters and possibly even does more harm than good.
I'm bored to tears waiting to hear if I can leave early, so on the matter of car horns, what say you?
(personally, I just use it to say, "Hey! You're a douchebag!")

Jeff Muttart, a traffic-accident reconstructionist, has pored over hundreds of surveillance videos of real-life car crashes and near-crashes. In 2005, he concluded that emergency horn use is not associated with decreased accident involvement. He found that drivers never steered and honked at the same time, and usually they didn't honk at all. About half of emergency honks were meant to chastise and came only after the danger was over. The other half were just preludes to a crash. "It really didn't serve any purpose at all. It was just, Hey, by the way, I'm going to hit you."
Also: We stink at honking. A 2001 survey for the U.K. Institute of Traffic Accident Investigators shows that most people take two to three times as long to honk as they do to brake or steer. Professional drivers, like cabbies, are a bit quicker—they practice. (Now that automakers are getting over the whole tiny-horn-buttons craze, honk times may improve.)
