I just found this on Jalopnik and felt it was worth sharing. Im still not entirely sure what it is, but I know its interesting and its footage that I’ve never seen before. It also covers a pretty cool year in F1 so you get to see Lauda, Andretti, Regazzoni, Hunt, Reutemann, Brambilla, Sheckter, Fittipaldi, Patrese, Munari, Villeneuve. Enjoy.
