The assumption that ATC wouldn't then watch the two known IFR aircraft collide.
Let's not forget the ADS-B mandate propaganda.
The contrasts in the system perplex me somewhat. I always
appreciate the effort to which Centre will go to alert a couple of VFR aircraft of our proximity to each other in G, but wonder why it's considered necessary. If it's 'necessary' in the case of two VFR aircraft in G because of the collision risk, it seems to me that it should be 'more necessary' in the case of two IFR aircraft.
It reminds me of why the crew of VH-NGA made assumptions about the weather at YSNF. Repeatedly fed good (and mistaken) news, but no one thought to double check that the crew had received the worst news about their destination (which news, even then, split the CASA FOIs down the middle as to whether diversion was required).
As soon as something goes wrong, everyone 'walks backwards' chanting 'pilot responsibility'.
