Animals crossing the street is rare, but a situation I'd expect self-driving cars to be trained on. I doubt they classified all known large animals, so shouldn't there have been a classification to anticipate animals it doesn't know crossing the street? As someone who spent a number of years living in the countryside, this seems obvious. However, for those growing up in cities, this might never cross your mind. It makes me wonder if there might be a lack of diversity on the teams building and testing these systems.
