You're missing my point. Many MR supercars have carefully designed side ducting that vents straight into the wake, which reduces drag. Some of them also have tricked out C pillars as well (Ferrari 599 not MR but a good example, McLaren 12C). It's almost like if you took the VW XL1 and moved its wheels way out with streamlined side pods designed to minimize interference drag. If they didn't have this the greenhouse taper would be useless because you'd get air from the sides spilling over.

The problem is that this ducting usually has a radiator, ram air inlet, or some other cooling apparatus in its way. Remove these, the fat tires, and downforce adders, and I bet a supercar would have lower drag than at least a Civic or something of that sort.
