Waymo and Cruise deploy in extremely limited public situations, including only in the middle of the night, and have been in the news a lot recently for a serious of crashes and software failures, some of which caused a pile up of around a dozen autonomous vehicles just blocking the road that had to be removed with tow trucks and employees. The scope of what Tesla is doing is vastly larger, more future proof, more reliable, and much more difficult to achieve.

Additionally, Tesla's model right now is to have a driver in the seat. They aren't trying to deploy a car without anyone in the driver seat. There's no need for them to have any license other than the one they have.
