The Tesla approach was kind of magical thinking; put enough data into the magic box, and eventually a perfect driver will pop out. In some ways it's similar to the "just make a big enough LLM and it will be GAI" thing (a model which has pretty much fallen out of favour even with the most relentlessly optimistic LLM vendors in favour of so-called reasoning models).
In reality, just shovelling data into a box is not sufficient.
