Any clue how to improve this to increas
aerodynamics while ventilating the cabin?
I am curious if the rear roof angle is ideal and if there is an ideal hole placement/size in the back to empty air into the vacuum behind the car from the cabin.
Edit this is **not** for an existing model car, but for a prototype I have built from scratch (see pic, which I have repost outside of Facebook to ensure it is visible)
