“It’s important to understand that in the Third World most driving is done with the horn, or “Egyptian Brake Pedal,” as it is known. There is a precise and complicated etiquette of horn use. Honk your horn only under the following circumstances:

1. When anything blocks the road
2. When anything doesn’t.
3. When anything might.
4. At red lights
5. At green lights.
6. At all other times.”
