It's not that we lack lidar, but we what we have in addition to "cameras".

We possess a spatial intelligence (e.g. how your brain has an approximation of: It feels like I walked three blocks) that will never exist in this "photons-in" "controls-out" fantasy.

There's a solid argument to be made that solving the self driving problem using only cameras might end up being roughly equivalent to solving the AGI problem because you will have essentially created a computer with a human understanding of the world around it using human senses.
I have thought that Tesla will be forced to learn many things from the only camera approach.

And they may well end up with something "that works". But... many buts.

What? An FSD Tesla has its very own "world model". It doesn't try to reconstruct a world "photons in", from scratch, 60 times per second. It continuously updates and refines the data it already has based on the sensor inputs, and then uses this internal representation to make driving decisions.

This "world model" is what you get to peek into through the car's screen. By now, it even has basic "object permanence". Nowhere near as good as a human yet. But AI is getting better, and an average driver isn't.
