Unfortunately the driving standard in Qatar is very poor, to be honest crap.

Even if you try to drive in a relaxed and defensive manner, the guy behind you will become impatient and start flashing his/her lights. But definately if you are in the fast lane and someone is driving as if he has a rocket up his backside, then you will do well to move out of his way. However, if the left lane is blocked, you may find yourself stuffed.

Also remeber to watch out for idiots on roundabouts who have difficulty staying out in their lane and tend to stray across lanes cutting you up, usually right to left. Regrettably it appears that people have difficulty using roundabouts. They are actually a good mechanism to keep traffic moving.

Unfortuantely giving way to other road users is not the norm here. The 'me first, get out of the way' mentality has got to change, until then Qatar will continue to experience a high number of crashes. Speed restrictions and radars are not the answer.

I doubt the guys doing the flashing as described in the posts above were British. In the UK flashing is usually to beckon someone or to give way. It is uncommon in the UK, if you are in the fast lane and for someone to flash from behind irrespective of how fast you are going.
