Emerging technologies introduce sociotechnical tensions that call for closer collaboration between technology design and policy. In this work, we introduce Design-Policy Adversarial Futuring, a scenario-based workshop method that supports design-policy engagement by structuring contestation between design and policy perspectives. We report on a workshop conducted in the autonomous mobility domain with 12 HCI researchers, used to explore and demonstrate the method in practice. The workshop illustrates how the adversarial futuring method can surface shifting harms, translate policy abstractions into situated use, and legitimise extreme ideas while maintaining grounded policy reasoning. This work contributes a reusable, exploratory method for supporting HCI-policy collaboration through contestation, which can be adapted across emerging technological domains.
