Not quite what you're talking about, but similar. The rear edge of the front wheel well is curved in for smoother airflow.
something like that at the bottom

the shape of the insight should be on every car as the upper rear "corner" of a wheelwell seems to be the place where a lot of air exits, unfortunately traditionally the shape is more scoop like then exit like.... fender vents and something like the insight might be a good thing

this image i googled up shows both airstreams....

both seem to be fed by the font grill... this might explain in part why a front grill block is so effective... it will reduce these turbulent streams wich will also effect the rest of the wake i think
