I believe the traffic congestion is not that bad compared to what I have experienced in Saudi..... except peak hours and at specific locations.... But as mohdata said: If you are a regular traveller, you'll find a way to manage that. Atleast its very good that I haven't seen or its unusual that a teenage is driving on the streets here in doha.................

Police is much more active and thanks to cameras installed at frequent intervals....... I believe if the mass transit system is deployed in Qatar (like Metro and other projects, the situation can improve alot....)
