It was an issue that Volvo experienced when they were testing autonomous vehicles in Australia. Someone mentioned it as a funny example during an interview and "the kangaroo problem" became a meme in the community. I'm not aware of any actual incidents, but Kangaroos are the most common cause of animal collisions in Australia, so it's not entirely off-base to talk about.
