UAE Road Safety

I commute daily from Dubai to Abu Dhabi, the speed limit for the highway is 120kph with signs indicating a maximum of 140kph. On a daily basis I see drivers sat in the far left hand lane travelling at speeds lower than the speed limit, with three clear lanes to their right. Is it really that difficult for people to understand that if you are not over taking then you should be in the right hand lane?

I am struggling to understand whether this driving behavior is down to ignorance or lack of education. Maybe the Department of Transport need to remove the magnets which seem to pulling these vehicles towards the central reservation….
