Of course. It's doing that by looking at the vehicle as the agent though; it has nothing to do with "the body language of this pilot suggests this vehicle will do X", it's just a predictive module because it's useless to be able to see another car if you can't predict it's going to go X units forward in the next time tick(s). Adding a layer that models human drivers to augment the prediction of this module you link would be a waste of time.
