Such neural systems can be embodied in machines with mechanic or any other forms of physical actuation.

The sensors are so sensitive, and the actuation is so quick that the system may correct direction before the driver reacts.

They are pretty common. And they're a little tiny robot, a simple robot with some sensors, a little bit of processing actuation.

And you're seeing a lot of things passing through its minds, a lot of self models that try to explain the relationship between actuation and sensing. It then tries to do a second action that creates the most disagreement among predictions of these alternative models, like a scientist in a lab. Then it does that and tries to explain that, and prune out its self models.
