I've only seen 2 comments about Tesla on this thread. But, it seems people underestimate Tesla on here (I'm not the biggest fan). Though they are having great progress in their FSD beta- one way to mark this is by the number of users with access to it, which has increased significantly. This allows them to collect a lot more real world data then their competitors. Once this gets better and is able to prove better driving than a human, which seems possible in certain metros at least as Waymo is doing, then they can do an autonomous Uber network of their Teslas.
But I think this is a smart move to join forces, and will give the consumer healthy competition in this space.
