Here is a film showing what traffic was like in Paris in the 1950s, ‘60s and ’70s. It’s a pleasantly nostalgic way to spend 19 minutes as you spot a variety of classic Citroëns in a truly french real world environment.
The title of the Paris Archives INA film is “Les embouteillages dans Paris ne datent pas d’aujourd’hui” (meaning; Traffic jams in Paris are not new).
The comparison with traffic in Tokyo is enlightening. And check out how they regulated Paris traffic flow (or rather — lack thereof).
At least urban planning in the middle of the nineteenth century created many large boulevards like Les Champs Élysées.
An entire 1hr 40 minutes movie ( 1961 ) Les Tracassins ou Les Plaisirs de la Ville on YouTube has a lot of driving scenes throughout Paris.
Googling La 2cv fait son cinéma has a lot of short clips.
