Ah, but you both forgot the two most important parts of driving in the Middle East:
2: High Beams
Now, you both mentioned them, as well as some of the more appropriate times to employ them, but you both missed the technique.
Unlike in America, where the breaks are activated by the pedal on the floor, in the Middle East, the brakes are activated by pressing on the steering wheel. This activates a loud siren to alert people behind you that you are about to slow down. Now remember your driver's ed: The horn- I mean brake, is never to be depressed fully and held. It is to be tapped vigorously and repeatedly, preferably while flashing your high beams and yelling obsenitiies in Arabic, Turkish, or Hebrew.
Also, beyond any of the situations mentioned above, both techniques should be employed early and often. Feel free to improvise.
