Does anyone know where the sunroof drain holes drain to in our vehicles. Bottom of front doors? Other places?

Drains into engine bay. on driver side goes through the firewall and comes out in the same areas as the brake fluid reservoir. You can see the painted "duckbill" opening. If you are seeing leaks it is probably stuck shut and needs to be flexed. BMW adds it so you don't get windnoise.
