For any radius to be calculable by the way geometry, *all* OSM turns
should be precisely mapped.  The  turning_radius tag however contains a
presumably correct value.  All other turns are presumably suspect.
I wanted to make some checks and this roundabout happened to be open
<http://www.openstreetmap.org/#map=19/50.57678/5.55340> in JOSM on my
desktop. View with Bing layer and see if the roundabout access curve
radius is calculable.  I didn't go further. I don't claim that these
values are useful to know, I say that the same happens probably everywhere.

Finally, I wanted this to be fun and a poor innocent was punished.

Please pardon me, Damien :-(
