It's interesting if you consider we have 2 eyes [cameras] and we drive under all conditions, and under bad driving conditions - if you're sane - you slow down or even completely stop and pull over with your 4-ways on. When I've been in very heavy rain downpours on the highway, it feels like I'm only driving because I'm able to follow the flow of lights in front of me as having a bunch of guidance points - autonomous vehicles could likely do a much safer job of this..
