Thank you for explaining this

Does this statement imply that the amount of drag at the rear of the vehicle is proportional to the
circumference of the area where flow detaches, and not its
surface area? I mean, the way I understand it is that drag forms along the 1-dimensional line along which airflow detaches and forms eddies, while the interior of that area is not in contact with the airflow so it does not directly play a part in drag. This would mean that the vectors of the force that is trying to slow the vehicle down are all based along the perimeter of where wake turbulance begins, not in the interior.
