You also have to know when it's not working correctly. If a RADAR sensor ices up, it doesn't work. It 'should' realize there is something wrong, but....... The same goes for any sensor put on a car. A human driver knows when the windshield has muck on it and they can't see properly. A camera or LiDar might not be able to tell that there is a problem.
