That troll only works on the motorcycle boards. 
Beats having a speed limit of 4 MPH and a guy walking in front of you waving a red flag.
I recently traveled to Chennai, India, where the horn is sounded constantly to enable the use of a kind of sonar. With no lanes, vehicles interweaving as much as seven wide, and very few respected traffic signals, the drivers navigate by sound.
Many cars have bumper stickers reading “please sound horn”.
It was insane! After a while though the sound became kind of comforting.
In India, this is no jest. Trucks have signs on the back of them saying “Honk horn”. Everyone, in every vehicle, spends more time leaning on the horn than not. I have no idea why.
ETA: Subcontinental simulpost!
::honk::
To agree with jjimm, it’s apparently mandatory in some countries. In Bangladesh, I once spent a four-hour bus trip with the horn going off at a minimum of every 20 seconds. I assume it must be a requirement of the law, or maybe to indicate the existence of other vehicles. Perhaps drivers are allowed to maneuver by echolocation or something.
I’ve heard of perma-honking in China too. My friend was there recently and couldn’t fathom why they would do that.
“Ghetto doorbell”
My friend always said the best way to get where you’re going is to hold down the horn as you leave your driveway and not let up until you reach your destination. Gets the slackers out of your way.
How else am I going to let my girls know that they need to slide up next to my fly Caddy and give me my money?
I can never seem to find the damn horn in my car when I really need it.
My first car was a 1968 Ford Galaxy 500. The horn was operated by a big, chrome piece that ran the entire way around the steering wheel. Ever since air bags became standard the horn has been relegated to a little button I can never find. Some ass will cut me off and I end up setting the cruise control.
True. The horn should really be able to be operated with a closed fist.
I only ever use my horn when pulling out of alleys. In traffic, my first thought is avoidance and by the time that is accomplished it is too late to think about honking.
I was told there’s a law that says when overtaking another vehicle (including a bicycle) the car doing the passing must honk its horn. You know, for safety. And more noise.
The India thing stands for Delhi, too. New Delhi is bad enough, but Chandni Chowk in Old Delhi is literally bumper-to-bumper most of the time, with bikes, scooters (three-wheeled contrivances) and dogs and pedestrians are always going through. My uncle used to honk his horn and then lean out the window and ask people to let him through. Sometimess the pedestrians would be walking faster than our car.
Other people’s horns have the magical ability to repair damage to my car.
I had a car with a problem that caused it to periodically stall when coming to a stop after driving at highway speeds. The only way to get the car moving again was to allow the engine to cool for a few minutes.
The car stalled when I was sitting at a red light in the middle lane of a 6 lane road. I put on my four-ways and waited for the engine to cool, as there was no way to get my car out of the road safely. While I waited, several people took turns pulling up behind me and honking rather than going around the obviously disabled vehicle sitting at the obviously green light. For some strange reason the resonance of their horns tootling melodiously did nothing to unstick the solenoid in my transmission.
More serious answer: In my area there is a small one lane tunnel that runs under railroad tracks at an angle. IIRC, there is a sign that directs one to stop and blow their horn once before proceeding through the tunnel to warn anyone on the opposite side.
Because someone had the temerity to drive on our freakin’ road.
This is a great description. Horns are welcome in many places…and even essential as one will keep drifting until someone gives him the warning beep. The beep is encouraged and expected. “Horn ok please”. No one gets road rage either.
In the U.S., it is a sign of aggression, even when used with sound purpose. 
The horn is the first step in road rage many times.
It’s not sporting to run over pedestrians and animals from the back. Honking the horn makes them turn around to see what’s going to kill them. :rolleyes:
I saw this story many years ago in one of those magazines where you copy something and send it in and eventually they publish it…
Seems a lady’s car stalled at a traffic light. As she sat there, trying to get the engine to turn over, someone in the line of cars behind her began to honk. Relentlessly. Throughout the green, waiting through the red, and then right away when the light turned green again. She slowly got out of her car, walked back to him, waited until he rolled down his window and said, “Sir, if you’ll go up front and start my car for me, I’ll sit back here and honk your horn for you.”
If cars didn’t come with factory horns, after-market car alarms would be more expensive, as some way of generating an obnoxious sound would have to be installed, also.
But seriously, in Brazil, as has been noted above for other countries, the horn is a communication device. “I’m right here,”, “Can I get by you,”, or “Get out of my way, asshole,” were all acceptable translations, which were obvious based on the circumstances.
