Interesting to me that even what initially looks to someone largely ignorant to aerodynamics like me as a very low effort design, like the Nissan Leaf, actually has some fancy aero design hiding in plain sight.

The handles are distinctly non-Tesla style, very pronounced, but they've tackled the wing mirrors actively by shaping the air with the headlights. https://mynissanleaf.com/viewtopic.php?t=6836

I expect as we see more small EVs (Small by non-US car sizes) built on native EV platforms, we'll start to see more adventurous designs for aerodynamic reasons as you can't hide a large battery in a small cheap car.
