We've already had a repeat of 2005 under pirelli or you forgetting the multiple TDs issued for tyres to make the race happen under their watch? Or the punctures suffered such as Max's blow out at Baku?
2005 only didn't happen because Bridgestone teams vetoed a speed reduction on one corner despite it being requested on safety grounds. Very very easy to prevent that veto or the need for it from happening again. And it's rubbish to suggest we haven't had similar last minute changes for safety reasons under pirelli.
You still missing the point that the tyres are artificially nobbled for F1, they are nowhere near optimal.
