Intermittent conversational prompts that require responses may be a solution. However, existing literature is limited with inconsistent findings. There is little consideration of NDRTs as an important context, despite their ubiquitous involvement. A method is also lacking to measure driver engagement at the cognitive level, beyond manual and visual engagements.</p><p><strong>Methods: </strong>Participants operated a partially automated vehicle in a simulator across six predefined drives.
