Probably a tough call either way Carl but as I am pretty sure there is a flag point between the right and left hander (turns 4 & 5) in the new complex a yellow flag should appear right in front at approx 25 secs on the first clip. I have looked and can't see one. Does that mean a yellow was not out despite several cars being off the circuit 1.5 corners ahead?

In the second clip the in car visibilty and camera angle are so bad that its impossible to see but at the approach to turn 4 there appears to be a green flashing light. Presumably the all clear from an incident further back.

Either way, the conditions were atrocious for both drivers and flaggies so some leeway needs to be given. The fundamental issue is that $6million plus was spent and clearly not on drainage.
