Hello, I added 2 turning circles here they are:     https://i.ibb.co/RjSXVfZ/image.png    
Node 26233616 and Node 26233652    
The turning circle in wiki is:     
https://wiki.openstreetmap.org/wiki/Key:turning_circle      
Which is more fitting than roundabout which has a traffic island in the middle: https://wiki.openstreetmap.org/wiki/Tag:junction%3Droundabout      
There is also passing place:    
https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpassing_place     
What do you think?      
Regards.
