While I was checking out the red sports car I realized that the isometric rotation view seems kinds unrealistic. The front wheel becomes a lot smaller than the real wheel as I rotate the view, than it would if I'm walking around a real sports car. I visualize it as some sort of 'high variance' issue in transformation.

Hi Nilesh,

In orthographic view objects are rendered only according to their actual size and not considering their distance from camera (viewer's eye). Therefore when the front wheel and rear wheel are of same height, but placed at different distances from camera, they will be rendered to span equal dimensions. 

In real life (assuming you are viewing from the front of the car) you will expect to see rear wheel smaller than the front wheel. That's how it's rendered in perspective view. But in orthographic view they are drawn of same height. Since our mind expects it be bigger than rear wheel, it appears smaller than the rear wheel. In that sense, orthographic view is by definition unrealistic. It's not meant to show objects as in real life, but in a way that will make them easy to design and modify with respect to each other.
