Yes lidar has limitations, but so does machine vision. That’s why you want both if you can have it. LIDAR is more reliable at judging distance than stereo vision. Stereo vision requires there to be sufficient texture (features) to work. It can be thrown off by fog or glare. A white semi trailer can be a degenerate case. It can be fooled by optical illusions.

Yes, humans don’t have built in lidar. But humans do use tools to augment their capabilities. The car itself is one example. Birds don’t have jet engines, props, or rotors… should we not use those?

It's because stereo vision is "cheap" to implement, not because theoretical biological lidar has a "ceiling".
