Gee, Fran, I don't see why the R&D can't be done while you are twiddling your thumbs (he says with tongue firmly planted in cheek.) Seriously, I think the progress of RCR and the array of choices you offer is nothing short of miraculous.
I was really just playing devil's advocate in asking the question. Some people, who haven't worked on or built a 2 seat, midengine, race based car don't have an appreciation of how difficult it really is to package any whim, dream, hope or desire into such a tight package.
