By not crossing the imaginary line between two subjects, left-right positions and directions never get confusing.
Dialogue scenes, two subjects facing each other, shots of moving vehicles.
Put "A faces right from the left side of the frame, and B faces left from the right side" in the fixed block of every shot. If it generates the other way around, regenerate, and use hflip only when there are no asymmetrical props or text.
Two-shot sequence, with an imaginary line between two characters that the camera never crosses: Shot 1, over-the-shoulder, a red-haired girl on the left side of the frame faces right toward a small robot; hard cut to Shot 2, the robot on the right side of the frame faces left toward her, same diner window light, 3 seconds each.
