You will have trouble finding genuine comparisons. As a recall, there were some press trips to Austin that compared Tesla Robo taxi to Waymo. But as with any press publicity, it can be a carefully curated experience. Even the much-publicized empty Tesla Robo taxis with no safety driver on board turned out to be followed by a "chase car."
As others on this thread have pointed out, there may be a lot less to Tesla Robo taxi coverage than has been promoted in the press, never mind all the Teslafluencers.
