    I wish Tensor the best, but I think this is going to be a hard sell.

    These videos exceeded my expectations. Tesla’s robotaxi rollout wasn’t perfect, but it went as well as anyone could have expected.

    But I don’t think Tesla’s accomplishments over the last two weeks—impressive as they are—mean that Tesla is ready to quickly scale up its service.

    Even if we assume all three of these crashes were Waymo’s fault, that would still mean that a large majority of the 38 serious crashes were not Waymo’s fault.

    So Tesla hasn’t found a different, better way to bring driverless technology to market. Waymo is just so far ahead that it’s dealing with challenges Tesla hasn’t started thinking about.

    But while access to more data is certainly helpful, it’s not a magic bullet. One issue is that the data Tesla collects is unlabeled.

    If Waymo vehicles were constantly asking for remote guidance, Waymo might need to hire so many remote operators that it negates the cost savings that come from not needing a driver.

    But the evidence for better-than-human performance is starting to pile up, especially for Waymo.
