Why can I see the wheel spokes on a car as it goes by if I'm not looking directly at it, but if I try to follow the wheels with my eyest hey are all blurred together ? Does the the brain only sample vision outside the center periodically so I get a strobe type affect?

Waiting at a stoplight and seeing the cars go by, if I just look at the intersection I can tell that the wheels of cars going by have spokes.  But if I look at a car's wheels themselves and follow them as they go by, the spokes are just a blur.  Does the the brain only sample vision outside the center periodically, so I get a strobe type affect?

The retina cells that register light and dark are more populous around your peripheral, and the retina cells that observe color are more populous toward the center.  The cells that see light vs dark are “faster” at processing changes than those that do color, so they can “see” rapid changes better than the color cells.
