They are called roundabouts, with logic dictating that they should be "round", however here in Muscat, a lot of our major ones are "oval" or if you were to track the movements of my steering wheel, sort of "splash or puddle" shaped things.
They are lethal. In Europe, you go on the roundabout (and it is round - they have instruments to measure that), you track the car in front and you lock the steering wheel to follow the curve and you exit.
Here, you take your eyes off the curve for even a second, and you are either in the wrong lane, or doing car-rolls into the flyover support at Lulu's (which is by far Muscat's most prominent ovalabout).
Please get them fixed. I see that you are replacing all of the ovalabouts on the coast road and at Qurum........well done!
