Could anyone give me an explanation for this line from
"Each road has to be connected with the roundabout in a separate
node—that is, between these nodes a segment of the roundabout is required."
I see no requirement for a separate segment:
* When a entering road shares a node with a roundabout then the router
knows it's entered that roundabout by reading the tags on the
* Whilst on that node, the router checks to see if there are any
suitable exits. If there are, then it leaves the roundabout.
* If not, it continues going around until it finds an appropriate exit.
