> I would love someone knowledgeable to give an estimate, but I would guess you need at least a handful (10+?1000+?) of examples of each edge case (involving bicycles, pedestrians, weird road designs, street signs, and so on) -- and there are many of them I suspect (at least 100s?). It depends on what sensors are in use and how the environment affects them. I can't get into much detail unfortunately, but I have seen radar systems that use naive Bayes classifiers for target detection and classification. Those systems required large numbers of examples across a large, multi-dimensional space to work effectively. Target detection and identification is a trivial task compared to what the control system of an autonomous vehicle needs to handle.
