Not clear yet what actually happened but a car that can drive itself autonomously was involved in a crash, which may be the first such accident of its kind.
Awesome videos - "Unlike many of Festo's flying robots, SmartBird doesn't appear to rely on lifting gas at all. It weighs less than half a kilo, and is capable of autonomous take-off, flight, and landing using just its two meter-long wings. SmartBird is modeled very closely on the herring gull, and controls itself the same way birds do, by twisting its body, wings, and tail. For example, if you look closely in the video, you can see SmartBird turning its head to steer."
