This isn't just a warning light - it's a sophisticated radar-based system that tracks vehicles approaching from behind at differential speeds. Unlike basic systems that only detect vehicles already in your blind spot, the Curvv's setup can predict if a fast-moving car will enter your danger zone within seconds. The amber indicators embedded in the wing mirrors provide clear, unobtrusive warnings without distracting from the road ahead. At night, the system automatically increases sensitivity to account for reduced visibility, making it equally effective whether you're driving through midday traffic or on poorly lit rural roads.
