Only the AF A380 CVR will give a good answer, did they actually see the comair aircraft ? and/or discussed would it be clear or not ?!?
This is the point I was trying to make earlier. Everything should be mentally/visually 'swept' clear at 150m.
What did the AF skipper register in his mind . . . where was his attention in those crucial 150metres?

There seems to be some confusion about how long the small aircraft was in that position, but assuming it wasn't long, the skipper has an absolute right to come to a standstill any time he is concerned that it may not be safe to continue. Just seeing that vehicle pass in front of him is just cause to stop and consider two main things: Is HE in the right place, if vehicular traffic is passing, and/or is anything else likely to be heading his way - and I don't mean the behemoth attacking from the rear!
If ever we find we're forced to press on into situations we don't like, just because we might get hit from the rear, then we'll know modern airports are simply no longer equipped for modern flight-movement numbers.
