Tesla is very far from having a reliable and safe driving system. 15 minutes of good driving footage is a neat tech demo, but for a deployable product you need 1,000,000 minutes of safe driving.
Tesla announced a couple of days ago that they had passed 1 billion(!) miles on FSD, and growing exponentially [2]. In Elon's master plan from 8 years ago, he wrote they expected 6 billion miles before more global regulatory approval [3].
It's not there yet, but it's far far closer than most people realize. Me, personally, I think end of 2024, Tesla can demonstrate 2-3 billion miles driven on FSD and that a self-driving car is at least 10-20x safer than human drivers.

It's already interesting if he does it in a big city he knows we'll.
Nonetheless the YT videos of the self driving stuff looks quite good.
You need to start somewhere and others are already doing it.
