I can't believe guys just can't turn their heads to the side or look down when a plane opposite them turns on a light so they can see what's on the ground in front of them as they taxi. And I really can't believe that any of you would intentionally "retaliate" and flash the other guy. That said, I'm courteous with the taxi light and don't illuminate it until pointed away from the other cockpit. But that has had me taxiing into position before when I really can't see anything at all as I make my way onto the runway. I'm not so sure that's real smart.
