Is it possible to transfer learning from vision to LIDAR? Maybe if it's possible to map visual images to LIDAR images and vice-versa (by running a car with both cameras and LIDAR and learning their associations)
Probably everybody does it for themselves. So Tesla tries to have solely vision FSD while Waymo I guess does what you suggest. However seeing with lidar is not like vision only. Maybe at somepoint they share their code as OSS, probably not or very late.
