I hope that makes sense.

They way it's drawn might suggest they come from the bottom of the car, while AFAIK it's the air flowing in from the sides, above the bulging rear fender.
On a Beetle, I'd seperate these 2 flows from the flow over the roof, and give the side-flows hard edges to detach from.
A hard edge under the rear bumper / extending a belly pan somewhat beyond the lower bumper line might not be a bad idea either.
