To resolve the cognitive uncertainty of self-driving transitions, I designed a Predictive Context System that transforms the vehicle from a complex machine into a proactive "Sanctuary". By replacing traditional menus with a Unified 'Opt-Out' Bento Card, I reduced cabin configuration from a multi-step task to a single intent-based confirmation. This system addresses the "Trust Gap"—the primary business blocker for autonomous adoption—by using Active Monitoring and Semantic Lighting to visualize the AI’s competence in real-time. This strategic proposal shifts the product value from a risky technical feature to a reliable, high-retention consumer service.
