Roundabouts often lead to cars being forced to stop. The stop is however generally much shorter, occasionally not needed, and when cars leaves at the first turn then the other cars from other directions can simultaneously use the roundabout at the same time. Many roundabouts here where I live also have extra roads for some direct right turns where such traffic flow is common, which mean that those cars don't even need to enter the roundabout and just need to be observant of cars existing towards the same direction.
