When I think of horrible traffic jams in France, I always picture the scenes from Julio Cortázar's short story "Highway Of The South." However, it's hard to beat Jean-Luc Godard's 1967 film Week End in that department, with this famous 7-minute-plus tracking shot showing an incredibleassortment of European cars. You'll see Citroëns, Panhards, Facel Vegas, NSUs, and much, much more. Thanks to SOS10 for the tip!
