Hello, I'm not really sure what to tag these parts of the road. A turning circle can only be placed for a point, not a line as far as I can tell. Also there isn't a circle at the end of it, it looks the same as any other part of the road.

Maybe they could be marked as a normal part of the road with a turning circle at the end if it?

I'm not really sure what to do, so if you could edit one as an example it would be really appreciated :)
