As The Verge reports, self-driving, i.e. “autonomous cars” (ACs) have a problem, at least in Aussie-land. They can’t figure out whether the kangaroos are going to jump or not or, if so, where to.
At least the Volvo company engineers recognized the kangaroo problem and admitted to it. Other AC proponents appear to be less cognizant or forthcoming at this time.
Perhaps the problem is even worse than you may have thought. The autonomous cars’ computers may not be able to differentiate between kangaroos, jumping mice, or any other “small animal” species with a tail -- or even between some without a tail.
