In spa there was a good 10 to 15 seconds from the first car crashing off track to the one spinning and being stationary on track. Another 5 until the deadly crash.

In this case its bot that much but still a long time before flags came out if any at all.

Its not the tracks that are causing these…

I'm not sure how much this would have helped here.

The first collision happened about a second after Bird crashed, and the second about 5s later. It will always take at least a couple of seconds for flags to come out, then the drivers won't be able to react instantly.

I think the problem here is visibility. In the most recent Spa incident, this was down to the weather. In this, it was just the layout of the track. Racing in situations where you cannot see far enough ahead to react is dangerous.

Same problem, it is not the circuit, it is the late deployment of the double yellow flags.

Like in Spa as well as here, after the first crash, the second one going sideways across the track was maybe not preventable. But if double yellow os deployed after that first one the oncommers at least can stop in time for the one that went sideways following the inotial incident
