You missed the analogy:

Darkness is to eyesight as inclement weather/obstacles is to LIDAR

[sqeaky]

Our eyes also come with our brains packed full of fancy algorithms to extract value from minimal information.

I am not sure what software does with noise from a lidar sensor but I have seen data from other noisy sensors and they are often useless.

What's the point of that analogy? Darkness can be fixed with lights on the vehicle itself. Inclement weather is entirely outside the control of the vehicle.

LIDAR doesn't work in inclement weather, that's the point.
