The voice guidance could tell you to take the xth service exit.

Or in your example [1] if you come from SW on Groppeler Stra├če and
want to go into the driveway, it could announce: 'take the service
exit next to the 2nd exit' or 'drive into the driveway next to the 2nd

Apparently, OSMR already skips service roads when counting roundabout
exits. In that example, travelling from SW to NW, it says: 'At
roundabout take 3rd exit onto Tecklenburger Weg'. However, when
travelling from SW into the driveway, it also counts the driveway as
3rd exit: 'At roundabout take 3rd exit onto unnamed road'. This could
be optimised.

In my opinion all the information for the routing engines is already
there -- i don't know how this should be tagged differently.
