The routing at http://map.project-osrm.org/JR is odd: The "Sharp turn left" doesn't make sense as one just needs to turn about 45 degrees.

The turn to the right is properly handled. If one reverses the driving direction, the wording flips: Again, the left turn is mishandled while the right turn is correct.
