Seeing the last shot on its own taken out of sequence does look a bit "raunchy", but the pictures were supposed to follow a story.
Shot 1: 2 guys drag race their cars, girlfriends look on.
Shot 2: Guy driving Challenger wins race (Duh) against Mustang, Mustang man's girl now fancies Challenger man. (Don't they always)?
Shot 3: 2 girls fight over Challenger man. (I know how that feels).
Shot 4: Mustang man realises he's lost, and leaves.
Shot 5: Challenger man gets the girl, and they fall into each other's arms on the hood of his beloved car.
