Furthermore, if you really want NLF (and have the CNC machinery to prove it), you can't just make your car's top+bottom "kinda look like a wing": no, you have to get a NACA NLF-series airfoil and match your car's profile EXACTLY to that specific airfoil (note that most airfoils are turbulent across the majority of the chord, yet those planes fly just fine).
Pretty tough to do in ground effect- just ask the Aptera boys.
