My point is that attached flow can cause drag. You state that only separated flow can cause drag. You are clearly wrong, as even a moment's thought about what I have written above will show.
And even so, the lowest drag forms have no separation, in spite of those resultants.
A car's got to be 3-dimensional in order to get inside. The air must be displaced as it passes. Some things are inescapable. And all that said, the achievable target is still on the order of Cd 0.09.
I'm just taking about the end game. The exit strategy for really low drag.
Ya gotta get a little wet in order to drink.
