Seeing all the damaged 3's on this thread makes me shudder! Here, EVERYDAY, rush hour morning and evening traffic contains about 70% impatience. Drivers here cutting other drivers off, not paying attention when lane changing, tailgating, waiting till the last minute to lane change...oh, and turn signals tend to be "optional equipment" here. So many accidents, everyday, and I sit here wondering "When me?" I can't tell you how many accidents I've avoided, thanks to the horn. Then, the driver you're trying to stop and help avoid an accident gets pissed because you used your horn. Whatever, I'm greatfull, just the same!
