On top of your analysis of commands that might flag conflicting commands, shouldn't we also be analyzing the radar to make sure there aren't any obviously conflicting paths?

I saw your comment about pilot intentionality being the major time-saver but in a situation like the Potomac River crash, the intentionality and knowledge may have been a unintentional headfake for a system like yours i.e "Yes I see the CRJ".

Maybe it's 80-20 for you, with the Potomac situation being especially rare.
