There's no reason to think the best performing, or even adequately performing, technological solution to a problem would mirror how humans have solved it. Submarines don't swim like fish after all.

But more specifically to this case, human eyes are attached to brains with (generally) vastly better image recognition and reasoning abilities than any camera based self-driving car. Because of this, humans are better able to recognize visual input even in degraded or unusual conditions compared with a computer.
