Can cameras do it eventually is a bit of a tangent.

All the information is there in a video feed, but the amount of work to get reliable perception from it is not small. With LIDAR and radar you get to the end goal with less uncertainty.

The real key is that things like LIDAR are designed to work well with the types of tasks computers are good at, like taking a bunch of precise measurements every second and performing complex calculations, while a binocular vision based understanding of the world is something humans are good at because we evolved that ability over millions of years.

You can probably eventually ("never" is a long time after all) get a computer to understand the world as well as a human purely through camera based sensors, but it's a much more difficult task than taking an approach that uses tools computers are already good at. Similarly, I suspect it would be an uphill battle to have a human drive using raw LIDAR input.

I think you underestimate how many guesses, approximations, and filling in your brain does to what you think you're seeing.

Absolutely. The goal of self-driving is to be better than human drivers. Even the best drivers struggle with the sun shining from low angles, or road reflections, or snow, and so on.
