I think Tesla is the closest on that. FSD works fine anywhere you drive. The initial Robotaxi service will be geofenced but that isn't a limitation of the system, as it is with Waymo. It is the next stage in the rollout.
They dropped v13 of FSD into China, with just training from publicly available driving video to learn Chinese rules and signage, and it has had impressive results. China will not let them export data gathered in China for processing on their existing neural net systems. They'll eventually have to do the processing in country.
