Do headwinds affect your speed more than tailwinds?

Talking of wings and leaning into the wind.

If you add a 'wing' just above you (does not have to be large) given neutral enough NACA profile (think NACA 0012 or something) it should have relatively negligible frontal and lateral drag, YET when leaned into the wind it should start to generate downforce for same reasons as streamliner sides generate lift. Add flaps and rudders to taste .

I'm not entirely sure how this system will behave when it comes to 'truck suck' though...

P.S.
Witnessing my inventions, my colleagues always joking that I, in fact, is inventing a spaceship to fly me back to my home planet Nibiru.
I'm not entirely sure how much of joke it is any more...

I'd also counsel that tripping the airflow into turbulence early isn't always a bad thing. It becomes a lot more predictable if you need a known amount of lift/drag etc.

I should note (for everyone's benefit) that turbulence does not imply flow separation (it can be the other way around). Been messing those terms up for quite a while myself .
