My husband is an optometrist. There are lots of people who are driving with poor vision. We do not need (although it is obviously better) perfect vision to drive a vehicle. We can drive in fog or heavy rain, with limited vision. I am not sure that image quality is a big factor here. But we do have a good spacial sense (distance) + object recognition (mass/speed) + psychology/habits. I can tell at glance if an object is able/supposed to move, and adjust (i.e. watch/sample it for few more milliseconds) to estimate it current speed. I estimate its mass and deduce inertia (can it stop if need to). I make eye contact with driver, to acknowledge that he saw me, etc. Not saying that those things cannot be learnt and used by a software. I do agree that we do well with just two cameras, and we make up for it. BTW, from our senses, one that I rarely see mentioned is the hearing (used to label and spatially locate). I do use it while driving (e.g. motorbike approaching, but not seeing it yet, or emergency vehicle).
