Not sure why you think so. If this is correct, there should be many other equivalent or better campaigns currently running at the same scale, right?
On the contrary, I imagine that data is a very significant limiting factor in this field.
Both data and computation are hard problems. AFAIK Tesla should still be leading in the former category by virtue of the number of its data collection devices. Crucially, they are collecting training data (real world human input) with which they will be able to train and test models.
Note, I am not saying that Tesla's current models are good, or that they will easily improve them. Only that you are too dismissive of the potential advantage that Tesla's data affords them.
