Just vision is a very reductive way of describing how we drive. We use sound to hear if something else is coming and where from, or if we're losing traction on the road, or if the road surface has changed. We can judge acceleration and deceleration in all directions using our inner ears. We can feel if the car's performing differently to usual indicating an issue with the car or different conditions. In addition when we are using our vision, if it gets obscured (i.e. snow covers the windscreen) we know how to get it off with wipers, and most importantly we're very adaptable to new conditions in a way that computers aren't, if we experience something completely new to us, chances are we'll make a reasonable in the moment decision.
