Well doing 90 here you can get away with. I wouldn't advise it in Baghdad due to the bad traffic problems here but out on the highways you can do it. Just make sure not to hit a pothole.
But for the most part the Iraqi's and Americans have repaired the major roads (they use) in Iraq.
In Kuwait the traffic laws are almost nonexistant. If you do get a traffic ticket it's about 100KD (around 350 U.S.) but very rarely will you see a car pulled over for speeding. They mostly just use cameras here.
