It also works at 1mph, but what's your point? IT DOESN'T DO ANYTHING USEFUL until well over 100mph. BTW, the Exige's front wing (which you assume isn't there) isn't on the hood, it's located at the bottom of the bumper-it's called a chin spoiler. And as for lifting bodies, they use the same principles, only they do it at much higher speeds, so they really aren't relevant to the satifying but not wickedly fast Toyota MR2. Just because basic mathematics apply accross the board doesn't mean their aren't some intriguing details to play with. Also, computers have a VERY hard time modelling fluid motion. It has to do with non-laminar flow (turbulence) and the sheer amount of points it has to animate to do so.
