if the framerate on a camera syncs up with the rpm of a rotating object, the object appears stationary

why can't we use this in real life to determine the "framerate" of the human eye?

The human eye doesn't have a "framerate" because it has tons of cells constantly sensing incoming light. The eye doesn't work like a video camera, which just takes still pictures very quickly to create the illusion of smooth movement

Then why do the wheels of cars look like they're spinning backwards sometimes?

I haven't ever had that happen to me so I don't think I know what you mean. Are you talking about on a screen or in person?

you're seeing the spinning under AC lights, flickering at 60/50 Hz

I found a good explanation from some pajeet on a question website, sounds sketchy but his explanation is fine.

He's talking about individual nerves transmitting signals so keep in mind the eye has tons of cells with lots of receptors each transmitting independently at the same time. They eye is just very different from video cameras

the human eye's "framerate" is variable and processed on a basis of usage / necessity as opposed to a fixed timer.
