Car horns

Here's something I've been idly wondering for a while. It's always bothered me when watching films or TV, when the heroine stops her car in order to fight the demon who's popped up on her back seat, and there is immediately a torrent of angry car horns. In my experience, car horns are a thing almost never heard. I've watched poor learner drivers take over a minute to manage to start up and leave a junction, and the queue behind is always entirely silent. So I thought I'd find out how people used their car horns, using the age-old scientific method of an LJ poll.

If you don't have a car at the moment, but had one in the past, feel free to answer in the past tense.

EDIT: One comment to this post included a word that caused the entire post to get blocked by my work filter. I did a second post asking if the comment could be edited, but it wasn't possible to do this, since it had replies. The only thing to do was to delete it, but this took the replies with it. So if you posted a comment which has now disappeared, this is the reason. Sorry about this!
