Big fan of roundabouts - generally they keep the traffic flowing much better than lights and work well for cars. However if I'm on a bicycle, or I'm a pedestrian trying to cross the road near them, they can be more dangerous. There is a special kind of roundabout that is designed to tackle this issue - the so called dutch roundabout ( at least in the UK :-) ) however it does require drivers to know how it works - so there is always a chicken and egg problem as you introduce them.
