I might be the only person at Gizmodo that likes Sphero's new Cars toy. My co-workers hate the way the robot announces it's going to sleep, and the long animated process it takes to wake up. They're also horrified by the very existence of sentient automobiles and tractors that moo. But my colleagues are too caught up in trying to understand Pixar's Cars world to realise that they're playing with the incredible future of robotic toys.
