Stalker research for our film - Skoda car advert

I saw this advert and thought it would be good for our research. The camera shots used in it are point of view and close ups of the people in the car who could be seen as the "victims". We could use these types of shots in our own film. I also liked the idea that in this you cannot see who or what is following and watching them, you can only hear noises which leaves it to the viewers imagination to who it is and what they look like. I think we should use this in our own film and not show the stalkers face so the viewer can make up their own mind on what he looks like.
Although this advert is not a scary one we want to make our film more mysterious and edgey.
