Saturday 23 March 2002 — This is more than 21 years old. Be careful.
After reading a Talk of The Town piece in The New Yorker about obnoxious car horns, I thought something I had thought while stuck in traffic myself: why do car horns have to be so loud? Over the course of my driving career, I’ve come to the conclusion that car horns should only be used to warn other drivers of danger, not to express anger or frustration. After all, what good does honking the horn do when stuck anyway? What are the chances that the problem is due to some recalcitrant driver who could move forward but chooses not to? Even if that were the problem, why would they move just because they knew you were angry about it?
Occasionally, a delay is caused by a driver at the head of a line of cars who hasn’t noticed that the light has turned green (I’ve done this myself, as have we all, I suppose). In these cases, I will briefly toot the horn to alert them, but will try (ineffectively) to give it a polite sound.
If the rule of using the horn only to warn of danger is a good one (and I think it is), then how about this: why don’t we make car horns that are quiet if the car is still (or nearly so), but are just as loud as they are now when the car is moving? Plenty of characteristics of cars seem to be adjustable based on speed (some adjust the height of the car off the road based on speed), so why not the volume of the horn? When a car is stuck in traffic, it could only make quiet beeps, sufficient to alert inattentive drivers, but not enough to cause real aggravation to others. Once the car is moving (and therefore able to get into danger), the volume would return to normal.
