In the west we're used to driving with relatively little driver to driver communication other than signal lights and brake lights. In countries where drivers use horns more, it really does increase communication between drivers about intention and whether or not another driver is willing to accomodate. For example in one country spent time in, to change lanes you signal (sometimes) but you usually just put your nose into the gap and honk. If the other driver is okay with that---and courtesy and etiquette means they most often are, they will let you in. If not, they honk twice back. It makes for a more orderly system in heavy traffic, if more noisy.
If you come to North America and do that, it will not end well. Horns mean little to North American drivers other than FU or get out of my way, idiot. And they are always in a hurry to get to the next light. Courtesy and etiquette are just not a thing, although maybe self-driving cars will fix that!
