Well, thus my point. A human interpretable signal would be nigh useless for robots in autonomous mode while an IR signal would be highly useful. But in tele-op, the human drivers could easily depend on the human interpretable signals instead of their robot sensing the IR signals. So the IR sensor would be potentially useful but no longer vitally necessary in tele-op.
