Parking inside a roundabout

Its an unsafe practice i found in GCC that vehicle are parking inside a roundabout at the outer edge. People are thinking that its a safe zone to park for a while and nothing wrong.In reality its restricting the vision of the other drivers who are about to enter into the roundabout. The authorities also not so insisting against it. Fortunately no any major accidents are reported just because of it. However its a practice which cant entertain. Hope the MOI will take steps to educate motorists on this practice.
