True tallg, there are some which are not the best designed, however IF the drivers actually switched their brains on then they'd be more cautious on those problem ones, instead of piling in & then getting all upset because of an accident.

In the Uk many large roundabouts are traffic light controlled, it ensures even traffic flow, especially at peak times.

Sadly many people here think that the moment they get behind the wheel of the car that they are in their own private safety cocoon & just don't use their heads & drive with complete ignorance to others around them.

If everyone had to negotiate roundabouts on bicycles or motorcycles, there'd be a lot less accidents!
