This was bound to happen
Having flown for both major carriers in Korea for a substantial time I can say that the " clear left/right " should just be a recording every time the aircraft senses a lateral acceleration and not a human callout.
They are too busy heads down looking at the ND giving verbalized readouts of your groundspeed as you taxi.
No-one looks out the window when you taxi.
This ridiculous scenario was borne out of the 'leaders' desire to fix a spate of docking/parking/rolling incidents. The solution? Invent yet another policy and "standard callout" .
Don't believe me? Here is what it sounds like;
PM; "Appoaching gater ...31, righter turn, grounder speeder ..9. A330, speeder 7... 6.. 5.. 4...4...3...2...2
..2.1. Approaching stoper. Steer lefter. Speeder..1. Turn righter. STOPer"
