Don't think roundabouts are a cultural thing but they are a nightmare to drive around in Qatar. Bahrain got rid of all its roundabouts and it is about time Doha does the same.
Mr.Landcruiser sees the roundabout and does not know whether to drive around it or drive through it :-) Mr Landcruiser also loves taking a left turn from the last lane in the roundabout.

Thought they would have demolished the jaidah roundabout - after one week of construction work no idea what they have achieved - it is still a bottleneck!!!! Three lanes merging into two in the roundabout etc etc etc....
