Very true. I have eyes which do not work together (called non-binocular vision) and hence I have no depth perception because of this. But I can still drive quite happily. The depth perception you are talking about is the ability of the brain to judge distance by using the differences in the image between each of the eyes. This is most pronounced at very close ranges, and decreases rapidly for more distant objects. For anything more than about 30 feet or so away, your brain will gain virtually no depth perception information from the above method. For anything not very near you, your brain will judge distances using simple perspective and not by using "depth perception". Also this "depth perception" actually relies on the cones in your retina (needs bright light), not the rods (which give you your night vision). So you will have very little depth perception at night anyway. For most driving, I suffer no disadvantage from not having depth perception, the only time I am at a bit of a disadvantage is for very close manoeuvres, like parking into a tight space. One of my hobbies is archery, which I can do perfectly well. I am however useless at fast ball games like squash, as it involves judging where a fast moving ball is when it gets very close to you.
