That's because people use it to signal irritation and then when it would actually be useful they forget about it. I was hit a couple years back as I was making a left turn. The roads were a little slick and the vehicle two behind me couldn't stop (the one directly behind me had no problem). The driver of this second vehicle swerved into the oncoming traffic lane just hoping that I wasn't turning left (despite the fact that I had my turn signal on). Had she used the horn in addition I would have known she was there soon enough to most likely prevent the accident. As it was, the first clue I had was when she slammed into my door.
