I'm trying to find a link where they discuss that aspect.
Please link and quote it if you find it before me.
On jet aircraft and on my hovercraft splitter experiments, wavy edges break up the sound nodes for a quieter top frequency level.
I have no idea what they are doing on this car.

No. 3 prototype SIM-CEL of SIM-Drive is a very bold design of course. Especially the back figure. Spoiler of wave type named Chevron spoiler is it. Result of (fluid analysis by computer) CFD, the effect of a small vortex is generated in the body near the surface, has a rectification effect that the small vortex attract the wake of the fluid in the outer, to generate a control rear portion of the vehicle body further that, some thing.
