I would imagine (hope?) that they'd treat side-mirror-replacement-cameras as a safety critical system. I guess the valid metric would be a comparison of chance of the side mirror camera system failing vs chance of your side mirror being knocked off by a passing car (or the auto-retraction motors activating unexpectedly)
