Did still nobody notice that the two most busy roads now can just plough through the junction without having to slow down at all?
Number one reason for crashes at the roundabout is people failing to stop short of either the stopping line or the car ahead. Just take a look at Kyoto's roundabout. Either, the cars just drive though or in case somebody actually slows down or stops to give way, you can be sure he's gonna be hit in the boot 2 seconds later cause there is always someone who fails to brake.

And even if these issues could be avoided by design somehow, you still have the disadvantage of having something like a 4-way-stop. So everyone has to stop/yield.
The current mainroad/sideroad configuration gives the advantage that the biggest traffic stream can pass the junction without having to give way. That's less stressful.
