Rocketboom has my favorite DIY car film of all time- C’etait un Rendez-vous by Claude Lelouch. In 1976 Claude mounted a 35mm camera and did a high speed drive through Paris. It’s 8 minutes, one take, it’s amazing. There’s a lot of speculation about how it was actually done, if he really drove and if he was really arrested at the premiere. Enjoy- Link.
