We know there are alot of stupid drivers in the area.. how come you just didn't yield and let him pass you, especially if you happen to be in the left lane where slower cars should give way. By holding your ground, you did stoop to his level. If an accident happened when he overtook you, you could have been badly hurt. It will take a long time before they change their driving skills and it is not worth the aggravation and stress. How did you know he was a Qatari?
