No. The router should know not to do this. Likewise as below the router
should not make u turns at traffic lights.
Based on what? How does the router know that the two ways are two
carriageways of a single road? Couldn't they be a straight road, that
becomes a oneway street at a certain point, and at that point a
junction brings to a oneway secondary road?
The name of the way, the fact that you are turning > 180 degrees on the
same way.
