Design a system that replays a recorded vehicle drive as an interactive 3D scene. A drive is a set of timestamped logs (sensor data, vehicle pose and similar) kept in object storage such as S3. An engineer opens a drive in a viewer and watches the vehicle and its data move through the scene, and can play, pause and seek.
Cover how log data gets from storage to the viewer fast enough for smooth playback, how you index the logs so a seek lands quickly, what you precompute versus load on demand, how the client keeps the different data streams in sync by time, and how the system behaves with very large drives and many viewers.
