How would a turbine that takes energy from the air current generated by a passing car decrease the energy of the car?
Not sure where you got that idea from, but how would that generate a meaningful amount of energy? It seems very unlikely that such a system would ever recover the energy spent on its construction.

I think it’s because you said, “Any system that gains some energy from a passing car,” not that anyone mentioned turbines explicitly.
