I may have something new to look at. With everyone enhancing the images, I decided to take a look at it from the original image on the LE site. I have done nothing but zoom the image. I didn't try to clean it up or de-pixelate it. I've noted what I see in the image. I don't see a driver... I think his face is behind the passenger side frame. I don't see a white tshirt... the white is simply the view through the driver's window.
But I do see something... noted below.
I will note that my first though is that it looks like a pillow in the window that my granny crocheted.
