The second image is a little more complicated version of the Ebbinghaus illusion. All three cars are actually the same size (they’re actually the same image repeated 3 times), but for some reason the cars further down the image appear smaller. At first, there’s no obvious indication why there’s a size distortion; there’s no official encirclement of the cars. However, looking at the image further, the street can be seen as an unofficial encirclement. The “smallest” car takes up the least amount of street while the “largest” takes up the most. 

Because this is a generated image (specifically the cars were replicated and placed) this specific event did not happen. However, with cars roughly the same size, with the same placement, and from the same point of view, a similar image could be observed in real life.
