text: Coming from M9 north and intending to use the roundabout to revert the direction and head again M9 north, the Osmand router suggested to exit A89 westward, perform a U turn and immediately exit M9 northward through the specific link.
  
  It could be argued that this was a router-specific bug, but I belive a no-U-turn restriction in any exit towards 2-way roads would avoid this possibility to any router and would also be a meaningful feature to the map.
  
  I will do it myself but right now I'm having some trouble with the online editor.
