Roundabouts can be too big or too small. The worst types are the retrofitted ones in tiny inner suburban streets installed as hazards to slow through traffic and the huge ones on massive lopsided intersections with more than 4 exits where you can't see the other side. Inbetween on light to moderate traffic intersections they are absolutely brilliant. They are a floral centerpiece at the heart of some Aussie country towns. One problem with them is that the large well functioning ones maximise the traffic through the intersection and drivers maintain a lot of their speed. It can be very difficult for a pedestrian to cross at them, particularly with children, compared with a traffic light.
