When driving in a car, the fact that light posts by the side of the road move faster across your eye than distant buildings do is known as the visual cue of linear perspective. motion parallax. relative height. occlusion. stereo disparity.

Motion parallax

Explanation: Motion parallax could be explained as the perceived difference in the speed of observed object relative to an individual's motion. Such that speed of objects decreases as the distance from our view increases. A typical example is the stated in the question above, light post, street lights and close objects by the road tend to move faster than mountain ranges, ridges or trees located in forest farther from the road side who appears to move rather very sluggishly. Motion parallax is usually attributed to the amount of distance the object moves compared to the percentage of the obsrver's field of view.
