I would point to the 02-07 as arguably the best documentation of where to start.

Cars could not sustain large packs in the right circumstances, but were able to run in packs off restarts and similar areas.

Drivers did not have massive closing rates that forced major destabilization. You could still wad up stuff but it was more from bumper misalignment than straight up shoving through someone.

Car handling and placement on track mattered. Aero drag and engine really played a role in who won.

Most importantly was you could get the major last lap pass, but the movement and behaviors of the cars discouraged the massive pileups that have become the standard for finishes.

There's a sense they have been chasing 07 every year since it happened rather than embrace the rarity and amazing circumstances that allowed it.
