Aisha summed it up better than anyone else. I furthermore believe it is firstly about personal maturity (or rather a lack thereof) before anything else. This is not something that is going to change soon, and yes, not all Qatari's drive this way but many do. There is a total lack of respect on Qatar's roads and it is amazing how many people adopt this driving style (even among the non-Qatari's)... I unfortunately have no appreciation for this kind of behaviour.
