I was told that these only delay the onset of vortex generation, and do nothing to alleviate it. I think it was Aerohead a few years ago in a lost thread.

Example:
M8F - 1971
The Cars: McLaren Can-Am Cars
*there's a minimum radius for leading edges,under which separation can be prevented.

*without longitudinal body camber you lose on drag


*without vertical side body camber we lose some too

*in this sequence you can see how edge radii mitigate vortex drag.When ever a body produces a difference in local flow velocities,the faster air will be at lower pressure and induce an inrush of slower,higher pressure flow,spinning up a vortex at the intersection.




*the autonomous delivery vehicle may be designed for low-speed,urban,surface street driving,where aerodynamics wouldn't have the impact as with a highway hauler.Don't know
