Piaf's death in 1963 led him to work with Jacques Brel, writing Je m'en remets à toi in 1964, and to writing songs for television shows such as Michel Vaillant in 1967, and cinema, Trafic by Jacques Tati in 1971.
Designed by Renault's corporate design department based within the company's Technocentre outside Paris, the Trafic was developed by the engineering team of Renault's light commercial vehicle unit at Villiers-Saint-Fréderic.
