A short film made in 1976 by Claude Lelouch, showing a high speed drive through Paris.

On an August morning in 1976, French filmmaker Claude Lelouch mounted a camera to the bumper of a Ferrari 275 GTB and had a friend, a professional Formula 1 racer, drive at breakneck speed through the heart of Paris. No streets were closed, for Lelouch was unable to obtain a permit.

It was later revealed that a Merecedes was used and the sounds were dubbed over. Here's part of the Wiki entry

Shot in a single take, it is an example of cinéma-vérité. The length of the film was limited by the short capacity of the 400 foot 35mm film reel, and filmed from a (supposedly) gyro-stabilised camera mounted on the bumper of a Mercedes-Benz 450SEL 6.9.[citation needed] A photo has surfaced that seems to reveal an Eclair cam-flex 35mm camera with a wide angle lens, and a typical "speed rail" hard mount - no gyros - on a Mercedes. This model, which could reach a top speed of 235 km/h (146 mph), was only available with a 3-speed automatic transmission. Yet, one can hear gear changes up into 5th, as well as heel-and-toe down-shifting with a high-revving engine indicating speeds of well over 200 km/h. Calculations made by several independent groups showed that the car never exceeded 140 km/h (85 mph)[1], while another[2] estimated that the car had peaked at 220 km/h (136.7 mph). Lelouch himself claimed that the top speed achieved was over 200 km/h, somewhere between 230 km/h and 240 km/h.[3] It is suggested that the sound was dubbed with the noise of Lelouch's Ferrari 275GTB, which has a corresponding number of gears and a similar engine note.
