Elon would like to have a word with you about that claim. On the Road to Full Autonomy With Elon Musk — FYI Podcast (rewind to 13:40 to 14:30)
I find it very hard to take anything said in that "interview" seriously, as the two breathless sycophants without technical understanding spent most of their time pumping words of self-praise into Musk's mouth. There was not a single follow-up to pin anything down.
e.g. @12:20
ARK: What makes you think this amazing technical feat [L4 sleep-in-the-back Autonomous Driving] is a solvable problem and why should Tesla be the one to solve it?
EM: I am an Engineer, I wrote software for like 15 or 20 years, I mean like I understand software at quite a fundamental level, I know what we need to solve to make FSD feature-complete, I think we've got an extremely good technical team, I think we really have the best people, it's an honour to work with them, and I am certain that we will get this done this year.
To which the obvious follow-up would have been "What has caused you to gain a better understanding now of what is needed for FSD than you had in 2016, 17 and 18, when you also made hugely optimistic predictions of imminent success?"
