General Road and Highway Discussion

Or just treat it as a four-way stop, which would rather defeat the purpose even if it resulted in fewer casualties.

Depends on what the purpose is.  Fewer casualties is at least one of the purposes of putting in a roundabout.  

But surely there is middle ground between full stop and not slowing down at all.  Quite frankly if some licensed drivers here are incapable of achieving that middle ground, then they really shouldn't qualify for a license.

I agree entirely.  Imho, a significant number of drivers in the Region simply should not be behind the wheel of an automobile.
