> eyes are way better than current cameras.

Strictly speaking, this is not at all true. Eyes are pretty bad at this, much worse than cameras have been for a long while.

Vision, however, is much better. This is because of all of the postprocessing our brains do with the raw information our eyes put out before we actually "see" what our eyes are pointing at. But even that is full of errors (think optical illusions).

It’s very true of the current automotive cameras. Just put them on a good display and look between the screen and reality. Source: I have done that.

The raw image your eyes produce is full of literal holes where there is no image at all (it's often referred to as "like looking through a slice of swiss cheese"), and the rest is mostly out of focus.

You don't see that because your brain does a ton of fixing up and filling in the blanks before you perceive things. Much of what you think you're seeing is actually your brain reconstructing things.

Yes, and in looking between the real scene and the display these errors are present in both.

Another reason is that we refocus and move our eyes constantly, giving us a more clear picture.
