I did listen to the full Ark interview w/Musk. I don't recall anything specific on the post Investor Day test drives. I did just go looking for anything on that. It seems odd I didn't find any independent. I was going by 'reported' responses....which...well, you know. Frankly I vaguely recall they had to fill out paperwork to get that ride which likely was NDA. Just as the employees testing had to. BTW, the 2016 vid, wasn't a test drive it was an ad and from what I read it was likely a heavily 'learned' route. It's clear you don't see it coming. I believe we'll see it this year. As for what SAE level it is...who the F cares. If I can get into my car, tell it to go to Stop & Shop (a local grocery chain) and worst case all I have to do is put about 1 lb of torque on the steering wheel to signify I am paying attn, I'll call that FSD. If I travel from New England to NJ or MD or PA and it successfully navigates the George Washington Bridge Plaza I'll call that self driving too. It'll take regulators, be they state or if Congress preempts regulatory OK, to allpw Tesla to drop "Beta" nomenclature and drop the nags. SAE doesn't get a vote on that. SAE levels are great for those taking engineering classes.
If I am wrong, you're allowed to say I told you so. If you are, I will say I told you so. My believing it won't make it happen. But, there are only so many times he can go back to that same well and if December comes and goes and there is no non-interstate NoA with traffic sign/light recognition, speed limit sign recognition, yield sign recognition, automated turn at intersections or going straight through after stopping... it will be reflected in the price of the stock, shorts will say "We told you so".
