> vehicle actually being used by hundreds of thousands of people and is slowly incrementally improving their self driving with massive amounts of feedback and data

Throwing data at the problem isn't going to solve it. Only people without expertise in AI think that's how it works.

I only ever see Tesla fanbase making outrageous claims like this without any supporting evidence.

Well, you are ignoring the point. The whole differentiating strategy between Tesla and everyone else is the incrementally improvement of large amounts of vehicles versus the magic “hey, we came out of nowhere and now just drive ourselves”. This has been repeated though out tech history and the incrementally improving real life one always wins.

The large number of vehicles makes it harder because you can't do hardware upgrades and a regression will kill someone.

And Tesla will just ingest large amounts of data from their fleet and magically dump an L5 solution one day? That's believable?

Elon Musk has been promising imminent L5 self driving every year for the past 7 years; that requires more than incremental improvement. The ones actually doing incremental improvements are companies like Cruise and Waymo, making it work one geography at a time.

The coca cola company sells even more units of non-self driving products than Tesla, and for a fraction of the cost!
