Alright: Here is the info from the IMDB trivia page, which is somewhat self contradictory.
The movie scores 8.0 on IMDB, which is exceptionally good.
* The film was shot in a single take, without any special effects or stuntmen, with the director driving the car.
* The idea for this film came to Claude Lelouch after hiring a gyro stabilized camera mount for a film he was working on at the time.
* While Claude Lelouch refuses to say who the driver was (although believed to be an F1 driver of the time) the car was his own Ferrari 275 GTB.
* The film is nine minutes long because the film cartridge in the camera could only hold 10 minutes of film and it was taken in a single shot.
* There was no confirmation of who was driving or what car he was driving. Sources variously claim the car to be either a Le Mans Matra 675, Ferrari 275 GTB, or, more recently an Alpine A110.
* Lelouch was arrested shortly after the film was screened but was later released without charge.
* The route taken in the film is 10.42 km long (6.48 mi). It takes the driver 7:57 to cover that distance, giving him an average speed of 78.64 km/h (48.86 mph).
