Hi, deepcosmos -- It does not work to say, *"They is an example of something." I'm not inclined to speculate on the psychological causes of the writer's grammatical error, which I do not think can be rescued by postulating inversion, though that is clever of you. Alas, the author did not write, "The self-driving car is an example of a joint cognitive system." That would have worked well.
Hello, David, this is a belated inquiry.
With the version - "An example of a joint cognitive system is self-driving cars, where a person turns on and off the driving." why do you think it doesn't work? Instead, should it be grammatically written, "An example of a joint cognitive system is that of self-driving cars, where a person turns on and off the driving"? If so, the existence - that of - is essential in this context?
Your another explanation would be really appreciated.
