OK now put a line of widebodies onto that taxiway and you will have a set of wingtip lights that are all around 100ft either side of the center line at close to 300ft apart along the 'taxiway'. Not unlike runway lights on a 200ft wide runway at 300ft intervals......
That is enough to trigger the 'illusion' of it being a runway - then the anti-collision lights on the aircraft would look like someone on the 'runway'.
You are not comparing like with like.
