Worst movie you've ever seen, that no one else should bother watching ever! And go!

I don't remember the title. It was a French film, from the 1970's, about a car show in Paris.

The cars that were due to arrive for the show were all stuck in traffic at various places in the city.

The movie alternated between scenes of traffic jams with cars honking their horns and scenes of the woman in charge of the show pacing around, looking at her watch, and swearing.

I suppose it was very artistic 🙄
