If two ways enter a roundabout at the same point, you can turn from road A into road B instantly, but going from B to A will require going around the entire roundabout. For a router to detect this, it would have to check (for every encountered node):
But "going around the entire roundabout" is what always happens. For clarity I'm reposting an example as many appear to misunderstand my PoV: https://www.openstreetmap.org/node/5408566797
1) is this a part of a roundabout? 2) if yes, which of the turns I can make here would require going around the roundabout?
These are tests that are performed even with segments between entrance & exit & so makes your points irrelevant to my point.
The current tagging of a one-way circular way is much easier for routing software to deal with and is conceptually "cleaner".
Who said *anything* about changing tagging? DaveF
