My take is that since many of us (me included) couldn’t see the double-yellow at S/F, they were not properly displayed.
However, we still screwed up, even if we couldn’t see the double yellows, because I thought that the only way to resume racing following a double yellow is to pass S/F with a green. There was all kind of circumstantial evidence (T1 incident cleaned up, field accelerating, etc.) that made us all THINK it was going green, but since we got the checker/white instead of the expected green, we still screwed up.
So, I’d say the flags that were presented were not visible to us, but given that we could see the checker/white we still screwed up by passing.
So, heads they win, tails we lose. We messed up, and that’s the bottom line.
I was the dumbest of all because I was many laps down and traded a potential 50% of lowest finisher points for a DQ! Whoever I passed, wasn’t for position, so it was truly lame!
