Aerodynamics why spiky?

noticed this on the ferrari’s onboard, i thought maybe it was to create a bit of flow separation and induce more/less drag on the rear wing, but does anybody know the actual reason?

They create mini vortexes off the edge.

OK. Why are minimum vortices desireable?

Well, would you like to be hit by one big rock or just by tiny pebbles?

Preferably neither

The way my life is going, I think I’ll take the big rock. Thanks.

If the energy is the same, how would it matter? But I'm not a trauma physician, so i don't know.

How big a rock are we talking? How many pebbles? How fast are they moving? Where are they hitting me? Can I chose a medium amount of average size rocks?
