It’s counter argument by example. Very Serious Scientists argued that heavier than air flight is impossible while birds were flying outside their window. Likewise, I am 100% confident that it is possible in theory to drive a car without the assistance of LIDAR or RADAR.

Does this mean current systems require this or that? Nope, but making the claim that all systems must be equipped with a certain technology seems short sighted, particularly when the proven counter example is putting a few million miles on the road every day.
