They're usually placed in such a way to prevent people turning far too sharply risking hitting someone in the oncoming lane, usually near the crosswalk. If people are having trouble with this they're having trouble with pedestrians too
I think I understand what you're getting at but your terminology is backwards - what you're describing is a wide turn. The obstacle is actually making people turn very sharply. Maybe my sense of scale is off, but the intersection in the picture looks it might even force some larger vehicles to make a three-point-turn.
From the look of these roads, there shouldn't be any vehicles so large they have to make a three-point-turn. If there are, then that's yet another indication these were needed.
