I wonder if technology could fix that, some sort of HUD display that signals a crash on a part of the track. Could update faster than it takes for the safety crew to get out there.
At 300kph you cover 83m per second. Almost a full football pitch.
In this instance the cars were less than a second apart. A HUD won’t help, human reaction times just aren’t fast enough. Doubt even automatic braking would stop in time.
