Update: Green are 2 different relations, so call it 1A and 1B - one (1A) is
towards Brisbane and 1B is towards Sydney. We are focusing here on 1B.
If you do not split the road, you will have whole roundabout I section TO/FROM.
I would have the 'to' as the exit road, not part of the roundabout.
The 'from' could be a single node of the roundabout.
Some will be coming from the unmarked road to the right...
Some may even be coming the wrong way having entered from a side road that has
only a connection to one side of the road that is a one way section before the
roundabout.
Thanks,

Honestly it would take too much time to look for these, but here's the example:

Please focus on a green relation, segment TO Sydney.
Thanks,

Anyway, back to roundabouts...
When approaching to roundabout, you will see at least one signpost which
informs you that you approaching to the roundabout. It will look like this:
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftiny
url.com%2Fuam667d&data=02%7C01%7Cv-nebrac%40microsoft.com%7Ca52744
1a54e645ec45e708d7dc691d9e%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%
7C637220216336463661&sdata=l80zq8dFvc6HbZmiqdhLhYIJxc1YahXtqBfRYPp
fms0%3D&reserved=0
and then, within the roundabout you have a new signpost which can be totally
different than it was before the junction:
https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Ftiny
url.com%2Fwagdlv3&data=02%7C01%7Cv-nebrac%40microsoft.com%7Ca52744

If you have two different destination signs then you have two separate
destination_sign relations.
The reason why do we split it into couple of ways is to properly put direction
where it is possible to see the sign for the first time.
You do not need to split the ways. If you read the wiki page you will find that
the members of the relation can be specified using the *nodes*
Davdson said, by OSM Wiki, everything is optional, except member "to". Yes, you are correct, but if you put both of these
relations in "to" - how could you recognize which one is before another? The other thing is that if you put first signpost in
relation with "to" member only (or with "intersection" and "to" members), but without "from" -
destination signpost would be displayed from ANY direction that you are coming from.
Do you have a real world example? If you do I can tag it for you, it's going to
be easier than trying to explain it.
