ELI5: Why hubcaps/rims seem to spin in the opposite direction when moving at high speeds

Is this a trick of the eyes (something to do with light), or an entirely different phenomenon?

Basically due to the strobe effect. Your eye can only see at a certain number of frames per second. You are capturing frames while the wheel is moving forward, *but* those frames happen at a time when the spokes appear to be slightly behind where they were in the first frame.

If the car changes speed while you are watching, you'll "see" the wheels slow down, almost stop, and then reverse to the correct direction!
