Group 1 - The event held by Fangcheng Leopard Automotive showcased its technical strength and driving experience, receiving positive feedback from media attendees [1][5] - Fangcheng Leopard's product lineup includes three models: Leopard 5, Leopard 8, and Titanium 3, with Leopard 5 being a star model featuring two intelligent technology options [3] - The Titanium 3 model has achieved over 10,000 deliveries since its launch in April, indicating strong market potential, with a weekly sales record of 3,371 units in the first week of June [3] Group 2 - Media participants experienced test drives of the Leopard 5, Leopard 8, and Titanium 3, highlighting the spaciousness, comfort, and advanced technology of Fangcheng Leopard vehicles [5] - The event reflects BYD's accelerating brand positioning towards the mid-to-high-end market segment, as indicated by the positive market response [5]

Core Viewpoint - The optimal solution for intelligent driving, according to Elon Musk, combines artificial intelligence, digital neural networks, and cameras, rather than relying on laser radar technology [2][6]. Group 1: Perspectives on Sensor Technology - Musk emphasizes that the global road systems are designed for biological neural networks and vision, not for laser-based systems, which can lead to conflicts between different sensor types [6]. - In contrast, domestic companies like Huawei advocate for the necessity of laser radar, citing safety concerns and limitations of camera-only systems, especially in adverse weather conditions [6][11]. - Huawei's executive, Yu Chengdong, argues that life is invaluable, and thus, safety features like laser radar are essential for reliable vehicle operation [7]. - Xiaopeng Motors supports a vision-based approach, with their senior director stating that the idea of laser radar being superior for long-distance detection is misleading [8][9]. Group 2: Limitations of Laser Radar - Laser radar, as an active sensor, has several drawbacks, including reduced signal strength and point cloud density at longer distances, making it less effective for identifying distant objects [10]. - The technology is also sensitive to weather conditions, with laser radar struggling in rain and fog, while millimeter-wave radar performs better in such scenarios [11]. - Overall, laser radar is characterized as having low information density and being prone to interference, making it unsuitable as the primary sensor for advanced driving systems [12].
