Automation addiction is a term used to describe the phenomena of operators' failure to handle
Handling exceptional situations depends on the cooperation between the machine and its operators: the machine provides information about the operators need to decide how to react.
In order to be able to decide properly and in time, the operators need to be practice the exceptional situations.

The Asiana Airlines Flight 214 accident of July 6, 2013 ( Wikipedia ) was due to restricting the Precision ILS approach, as the instrument landing system's vertical guidance (glide slope) on runway 28L was out of service. The pilots had to land manually, but they did not practice manual landing sufficiently, and failed.
