I've not driven in many countries as you have but from my experience
Qatar is very safe.

Here is where I've driven.

UK - Other cars drive so close to you and don't slow down when they're driving TOWARDS you
Shanghai - It is crazy! The lines on the roads mean nothing. People will bump each other and then carry on driving
Bahrain - actually pretty good! Except for when the Saudis and Kuwaitis come. They seem to think you're supposed to drive ON the line.
Egypt - You'll go Deaf before you arrive at your destination. Honking has it's own language!
Qatar - I only have some trouble on round abouts because some idiots go from lane 2 to lane 1 to lane 2 (Road - Roundabout - Road)
France - I didn't even bother to try.
I've driven in other countries like the US, Belgium, and Spain and they're alright.
