To drive successfully, we don’t have to understand, or even perceive, the complex machinery of our automobiles. The hidden complexities of our private cars only intrude on our consciousness when that machinery fails, or when we collide unexpectedly with something (or something with us). Even in the case of mere mechanical failure (to say nothing of a serious accident) such intrusion is always felt, at least initially, as anxiety-provoking. That’s a consequence of emergent uncertainty.
