Generate a minimalist terrain-style animated driving route video (MP4) from a list of stops (cities/POIs) without Remotion. Uses OSRM for road-following geometry, OpenTopoMap terrain tiles for basemap, Matplotlib for frame rendering, and FFmpeg for encoding. Use when the user asks to create/export a dynamic self-driving route map video (fly-follow camera, route draw animation, labels) and wants it along roads/highways.

根据停车点列表（城市/兴趣点）生成极简地形风格的动态驾驶路线视频（MP4），无需使用Remotion。采用OSRM计算道路路径几何，OpenTopoMap地形图瓦片作为底图，Matplotlib渲染帧，FFmpeg编码。适用于用户要求创建或导出沿道路或高速公路行驶的动态自动驾驶路线视频（飞行跟随视角、路线绘制动画、标签标注）的场景。
