Must disagree on your blanket description of Qataris. Do some break the various traffic laws and endanger their children? Yes. There are also loads of expats (including those who supposedly know better i.e. Western) who do the same.

I work with Qataris every day, some are good, some are great, some are not worth my time - just like my fellow Canadians. I have found that most of the people I encounter (of any nationality) have a great sense of humour and will smile at you if you smile at them. Often I find I take others by surprise (students on my campus - they are not in my class but I encounter them out and about) by saying Good Morning, how are you? with a smile. It's not something they're used to - and it goes a long way to establishing a rapport anywhere in the world if you are sincere.
