Wikis are fine, Moreack. I tend to agree with you, but I wouldn't say I'm absolutely certain there is not a person in the back of the truck.
When I first viewed the photos shortly after they were released, I briefly scanned each one, taking in the whole image and not focusing on any one particular area. Then I read a comment from someone who said they could see Lauren in the back of the truck. I took a second look, and immediately saw a shadowy figure of a blonde haired woman sitting up with her back against the rear window, and her arm resting on her bent knee. Her body language was very open, and my mind interpreted a woman who was alert, comfortable, and enjoying the ride. I expected to see something quite different.
There has been a lot of effort put into enhancing the photos to clarify physical details, most of which I can't make out. Still, the work is impressive, and I give kudos to those who have taken the time to do it. Besides recognizing shapes and forms, however, I'm interested in perceptions. As in the case of pareidolia, it's not necessary for each physical attribute to be accurate in order to get an impression. The back of a clock can look like a frowning face, as in the wiki photo. So, other than physical details, what do people discern from the images? What is the mind saying about the scene? I haven't read much discussion about that, and although it's subjective, I think it would be interesting to note.
