Why can our eyes smoothly scan a moving object like a passing car or the ball at a tennis match (when our head is still), but if we try and duplicate that dynamic without a moving object they, move in big individual movements?
Seems simply to be an involuntary / voluntary thing, but it still baffles me.

Because your brain fixes your vision in your head after the fact.
Your eyes are actually constantly moving small amounts in random directions. You don’t notice becaue the brain decides it isn’t important, so what gets “seen” by your brain doesn’t include that motion.
For tracking an object, that became a skill that was useful for our survival, so our brains developed the ability to do that efficiently. Forcing your eyes to do the same motion without that input mucks up the already-established algorithm, asking your brain to do something it hasn’t practiced much.
