Hmm.. Randomly generated real-world traffic based from traffic sensors and cameras. The key here is, if they use the same data and feed every car the same, then it can be easily gamed with overfit techniques. The better question is, what happens if you give the AI car a no-win situation? How does it handle it? The Kobayashi Maru can be looked at as a way to detect outliers and failure modes... even if the game is rigged.
