White Line Fever is about an idealistic young trucker (Jan-Michael Vincent!) trying to make his way in the cutthroat and corrupt world of trucking. After he refuses to take a load of cigarettes and slot machines, he gets his ribs broken and can't find work anywhere. And then he gets a job by waving a shotgun around. You know, that old chestnut.
See, in this movie the Trucker Uprising is justified by the Evil Police being in the pay of the Evil Cigarette and Slot Machine people.
And then the movie's Roger Corman origins take over and you think the movie's going to become a big old truck chase with trucks trying to stop the Blue Mule (that's the name of the truck) and people on top of trucks with shotguns and every crash shown from multiple angles. Then Dick Miller shows up and you know you're in for a good time. Alas, after a single car crash/explosion (shown from several angles), it degenerates into long, scenic shots that eat up the running time and shocking talk about controversial issues like abortions. And then there's a courtroom scene and the movie starts being about domestic problems because exciting driving scenes cost money.
I don't know why White Line Fever rated an explicit callout in Death Proof, since there really isn't that much driving in it, and none of the stunts really struck me as something you'd feel the need for CGI to recreate. On the plus side, there's a scene where the bad guy tries to kill the hero with a forklift. So that's something.
