Abstract
We propose the concept of directive driving automation that positively influences drivers’ intentions to achieve shared goals. As a step toward directive driving automation, this survey study explored how social norms can persuade drivers to continue using driving automation. We tested social norm messages using a 2x2x2x2 factorial within-subject design: norm type (descriptive vs. injunctive), explanation (absent vs. present), spatial scale (local vs. global), and outcome criticality (safety-critical vs. non-safety-critical). The results suggest that framing messages as descriptive norms and providing explanations relevant to the driver can encourage them to continue using automation, especially with safety-critical outcomes. This study highlights the importance of considering message characteristics in persuasive interventions to promote the safe use of driving automation.
