I doubt anyone can prove it in a real-world scenario where other variables lead to more variation than the gain you may hope to see.
Tinting affects the AC, ventilation, or the opening of windows, which in turn affects FE - so it's very indirect.
The effect is also temperature-dependant and seasonal - factors which will only add more, and more important variables.
Proving this on a car will require a far more controlled environment than the wide open road.
It's a bit like MetroMPG's experiment with airtabs: they definitely smoothed out the airflow on the back of his car - which should have a positive effect - but under his test conditions he couldn't prove they effectively reduced his FE.
Would NASA list them as a spin-off of their research if they didn't work ... for their intended purpose ?
