CurveCall

On difficult mountain roads, safety often depends on experience. Local drivers know which bends tighten unexpectedly, where visibility drops, and how the road flows. Novice drivers don’t know this and that uncertainty can be dangerous, especially in fog or poorly marked terrain. CurveQ breaks that barrier. Using GPS and road geometry data, CurveQ acts like a rally co-driver, providing simple voice guidance about upcoming curves — sharp left, sweeping right, tightening bend — without requiring the driver to look at a screen. We built it with Opus using multi-agent teams to refine look-ahead distance, velocity-based adjustments, and narration timing. Verifier agents tested different road scenarios to ensure guidance was helpful, not overwhelming. CurveQ turns expert road familiarity into accessible, real-time guidance — putting safer mountain driving in everyone’s hands, not just those who already know the road.
