I think you pretty much nailed it with basjoos Civic.Obviously,Honda could of had a little more roof camber than they did,but Mike doesn't have any control over that and has integrated his tail very well into car.Going "outside" means a little skin friction penalty,way better than going "inside",which would impact form drag.Sure,you can nit pick the details but basjoos has scored an out-of-the-park home run!
