I expressed it poorly. I had to have stated, "Traffic traversing the dual carriageway and turning right (the camera vehicle), or traffic approaching from the left and turning right off the dual carriageway (in the path of the camera vehicle)." Both feature double broken give way lines.
The vehicle approaching from the right should solely proceed in a straight trajectory.
In the street view, advancing one step in the camera vehicle should reveal the issue, hopefully. The camera car seems obstructed, and if you shift the view to the right, they are in the trajectory of an oncoming vehicle on the primary roadway.
The aerial perspective enhances the visibility of the junction's configuration. I have consistently found this type of intersection perplexing and have never really comprehended the priorities in this context.
