I looked at the 3 articles which followed in post, the ieee one addressed that after commenting on some Kangaroos being out loose here in the US,It's not just about wallabies and kangaroos!
Secondly, kangaroos are, everywhere but in Australia, a good example of autonomous cars' long tail problem (heh), which suggests that as the number of possible driving situations you may encounter approaches infinity, the probability of encountering those situations approaches zero. In other words, lots of weird stuff could potentially happen, and there's no way to predict all of it. If you're driving around in the United States, encountering a kangaroo would be very weird, but it's by no means impossible: here's one that was running around eastern Oklahoma in December of 2013:
I’m sure kangaroos are farther down the list, but it’s a list that's infinitely long, and there’s no clear point at which a potential situation goes from “worth preparing for” to "not worth the effort.”
“Don't hit things” is useful, practical advice that tends to be pretty high up on an autonomous car's generalized priority list. However, there are many different ways of not hitting a thing depending on what that thing is, and sometimes that advice can even cause problems if the car senses something that it doesn't understand.
