> More sensors help, but passed a point it's extremely marginal, plus you're throwing the majority of the raw data away anyway. Unless other sensors break, then they're suddenly useful redundancy. In a safety critical product like this, that alone should preclude the removal of sensors. > But there's a reason humans only have two eyes and not three or four, for example. Two eyes are really all you need. You still get two, both for depth sensing and for redundancy; and some animals like spiders have 6-8 eyes.
