The eyes see what the eyes wanna see. That grainy image with a circle highlighting a blob on the edge of the track is far from conclusive.
I think everyone of us here have agreed that no-one wants the season to end like this, so let's hope it all blows over.
Even if some people don't see a green flag, logical deduction tells us there was. There must be a flag being waved at that marshall post at that point, regardless of color.
If the yellow zone was to be conintued, yellow must be waved as a repeat there.
if the yellow zone was to end, a green flag must be waved to signal the end of yellow.
Basic marshalling rules on any track.
Certainly it should be clear (also comparing footage of when there was a yellow flag) that the marshall post did not wave yellow at that moment.
