Why is there no country where you have more terminating-road-priority intersections as opposed to continuing-road-priority intersections?
Example of terminating road priority: Road A terminates at an intersection with Road B. Road B has to yield to vehicles turning onto Road B (especially cross-lane turns)
What you’re suggesting would require a stop light + sensors to be done safely. That costs much more than just putting up a stop sign on the road that is normally empty.
What would happen if a yield sign were put on a 2-lane continuing road (1 lane per direction)
