A roll of yarn and Scotch tape would tell.
Even if they did, a fence cannot alter the velocity and pressure gradient for the local region of flow.
Transverse flow isn't an issue unless some horrific vorticity was created. I don't see that for Saturn. CAR and DRIVER aero tested all of them, and they represented some of the lowest drag for their market segment.
To reduce drag, flow must decelerate, and build pressure. That can only happen at the back of a car, allowing that you've cleaned up all possible rough areas along the way.
'The main contributions to the drag force originate from the rear part of the body.' Dr. Wolf Henrich Hucho
