Wait what's the illusion?
The random-looking black and white "buldings" on each block have some very not random "curves" of contiguous white buildings. When you look at other parts of the image, your peripheral vision may interpret these white curves as the same thing as the perpendicular green "roads", giving the illusion that the roads are no longer all perpendicular when you look away.
