There's a whole chain of this thinking in SF. Asimov was the first to use the analogy in the 1950s though he never chooses the exact phrase "traffic jam":

Pohl in the late 1960s acknowledges that he isn't the first to have this idea, but does actually use "traffic jam": “Somebody once said that a good science-fiction story should be able to predict not the automobile but the traffic jam”

I rather like Heinlein who a little earlier (1966) suggests SF would have predicted something more interesting, instead of car -> traffic jam, Heinlein says good SF would have predicted car -> teenage fumblings in borrowed car.
