Yellow should be followed by a Green. Yellow and Red (I assume you’re meaning the Slippery Surface/Debris Flag) does not need the next flag point to display a certain colour and if there’s a Red Flag out on circuit, all points should be Red.
I really don’t know how to explain this more than I already have.
The situation we have here is a Yellow Light on drivers right, and a debatable flag on drivers left. If it is a Green Flag being displayed on the drivers left then the pass is legal, no questions asked, there’s always going to be a delay in the timing and reactions of the lights. If, for some reason (A reason that is unknown to me) the sector needs to be under Yellow Flag Conditions, then the whole “Floppy Markers” situation comes into it, which is what I explained earlier. (I can draw a diagram if it’ll help some people wrap their minds around it.) Either way, the pass, down to where it happened on the circuit and ignoring what flags people think they see, is legal.
Now, people can argue about what flag was waved, and what the .gif did or didn’t show till the cows come home, it doesn’t really change the facts of this so called “Incident”.
