Having lived 5 years in Kuwait I personally think Kuwaiti's are the worst drivers I have ever encountered.!
If you are in the fast lane on any of the freeways and are going too slow by their standards they roar up behind you, sit about a foot off your rear bumper and stay there until you move over.
I saw this once where a police cruiser was in the fast lane doing abt 140 clicks and a Kuwaitii in a jeep cherokee screamed up behind him, sat about a foot away and stayed there until the cop moved over to let him pass !!
You could not drive into the city without seeing a new wreck on the side of the road every day.
