100 years of Indy race car improvements in aerodynamics
Great video of Indianapolis 500 aerodynamic advancements throughout the many decades of Indy race car design. See great Computational Fluid Dynamics illustrations and animations.

...the very first rear-view mirror was an aerodynamic device/wing deflector!

The Lotus 38 has an internal duct to air curtain the open cockpit.  |

Colin Chapman wanted to challenge Indy traditionalists, he brought the Lotus 38 in traditional oval track bad-luck color, green. Besides the super-lightweight monocoque engineering, offset suspension lengths (aero-bad) and mid-engine configuration, he tried an aerodynamic experiment. He called it 'dual windshield'. See closer @ 4:58. Air from nose opening is ducted in between two layers of clear acrylic windshields to create an 'air curtain' or bubble over the cockpit. Combined packaged, decreased 10% drag compared to Kurtis Kraft competitors.

And with a yeller stripe down it's back.
It'd be hard to separate them out from the whole cars, but I wonder about the relative downforce from the Marmon Wasp rear-view mirror vs the Chapman dual windscreen. |

The opening video is a refreshing take on the subject.
I mean this in context of all the poo-pooing open wheel and race cars get in this forum (I'm sure for good reasons).
The closing comment about the car racing rule makers having a major influence on the future direction of aerodynamics in racing was well placed.

I saw a T-shirt at the Bug-run this weekend that said "Warning: I do stupid things". And this Berry T that had radically trimmed Model-T style fenders:
Also (Tesla's Falcon doors have nothing on this):

That's pretty close to a Meyers Manx style body.

Have a look at Smokey Yunick or Jim Hall. Sometimes you have to make your own loopholes in the rules.
