Humble pax here who doesn't get to see out the front. Everyone has talked about the green centreline lights on the taxiway. How many of them would have been visible, with four large aircraft lined up on top? Is it possible that only fragments of green line would have been discernible?
At night, with less visual information, the brain has to extrapolate from the visual clues it has, and wrong patterns can be made. I've certainly misinterpreted the road ahead when driving at night.
