I've read through all the post on this discussion so far and I totally agree with Darrin. I also think all roundabouts including ones paint on the road should be drawn as a loop way. I see the discussion has been about trying to define what a roundabout is. But no one has thought about the end products that this data can be used for. There are many programs and devices out on the market that when the OSM data is converted into a format that that the program or device can use, that the mini_roundabout tag is lost while being converted. It basically turns that intersection into a four way intersection and you have no idea that there is a roundabout at that intersection. A really good example is all Garmin mapping GPS. All roundabouts HAVE TO be drawn as a loop way to show up on the Garmin GPS. I can't be 100% sure but I would this would be true for most mapping GPS's. So what I'm sayings is you are better to draw a loop way for ALL roundabouts so that if the tag is lost while being converted to another format or load into another program, any Tom, Dick or Harry can still tell there is still a roundabout at that intersection.
