That is what worries me about this new rule! This is just going to cause more bad wrecks. IMHO. lol
They ought to adapt the "local yellow" concept from the road courses; let the guys race to the line until and unless they hit the area around the wreck.
The other "unintended" consequence (in my conspiratorial mind) will be an increase in mysterious "debris" cautions later in the race when top teams find themselves just over a lap down.
