While I agree that the quality of this method is impressive, there are two caveats: 1. We do not know the set of pictures that the authors did not show us. So maybe this technique works really well only for a small fraction of cases. 2. Games (especially games that involve moving cars) tend to simplify mechanics so much that the moving end result will never look realistic, regardless how perfect the still picture is. So yes, I expect great outcomes from such a method, but I don't think its going to be a revolutionary silver bullet.
