motion parallax

Motion parallax is a depth perception cue resulting from our movement. When you walk or drive, objects close to you appear to move rapidly in the opposite direction, while distant objects seem to move slowly or stay still. This difference in apparent movement helps your brain gauge how far away objects are. Essentially, the closer an object is, the faster it seems to move across your field of vision as you move; the farther away, the less it appears to shift. Motion parallax is an important visual cue that helps us understand spatial relationships in our environment.
