Just slapping on a lidar doesn’t simply solve that issue for you either. Making out individual objects from the point cloud data is equally difficult plus you’re then having to deal with cameras too because Waymo has both. I don’t see how you imagine having Lidar and cameras would be easier to deal with than just cameras.

Also. Tesla already has more or less solved this issue. FSD works just fine with cameras only and new HW4 models have radar too.
