i wish the few roundabouts that large here in texas were so well painted and defined.
to contribute, this is (best picture I could find, google-fu is weak it is) intersection of us75 & sam rayburn tollway, cloverleaf with 4 different turns. two have about the same radius but differing yaw pitch (if that is right term). the NW corner the pavement slopes from hi to low inside to outside (off axis), and SE corner hi to low outside to inside (best grip)
