I remember years ago, Traffic violators vehicle numbers used to be published in the News Papers. That should come into force again.
It is not only the locals that break the rules, but idiots follow. And if you consider the local population, it is a fraction of the expat. hence the stream of vehicle are majority expat.
I hasten to add, I am sure violations happen all over the world and I am sure I commit some violations too. I live and work in Qatar and treasure my life, hence the comment and feed.
