Years ago Waymo bet on a completely different self-driving approach compared to Tesla: putting a big expensive LIDAR on each car so that their self-driving model has tons of reliable 3d distance data, instead of only using comparatively cheap cameras and having the model infer everything from that. Now that testing results are in, AFAIK the conclusion is that the Waymo approach actually works (driving safer than actual human drivers) and Tesla's doesn't.
