And I can't find any examples of super-high efficiency, low Cd vehicles with ricer-scale, befinned diffusers on them!
EDIT: wait a sec ... Fog of memory is parting... I think someone's going to post a pic of a solar car that has 'em.

I tend to agree with you overall observations. I was just kicking the idea around.
Formula 1 cars have been productively using various diffuser fins for several years now, but I'm not sure that the 150-175 MPH difference in speed makes that comparison relevant.
And, yes I remember seeing that solar car. As I recall, the fins were small and at the very rear.
