No, he didn't feel the same way in 2016. For a long time, he's thought that FSD would be achieved around 2020-2021.
Uhm... You are right, I can't guarantee what he was feeling, I can only go by what he was saying, like FSD features to begin rolling out by end of 2016 (while not even automatic headlights or wipers worked by end of 2016) and Elon's
video on their website showing FSD and a claim that Tesla will demonstrate coast-to-coast FSD by end of 2017. Maybe you are right, maybe he didn't actually feel that way, instead was plain lying to people while showing fake videos to get more people to pay for FSD. Maybe he still is not feeling this way today, just lying?
When he says FSD, he just means you CAN have the car drive from point a to b in any routine USA driving location. He doesn't mean it'll be able to do so every time, all the time, etc.
Really? Did you read the description of FSD Elon was selling in 2016?
Did you not see
Tesla marketing video showing the car driving itself through city streets, intersections, roundabout, parking itself, etc? That was all part of 2016 marketing.
He also admits he was hoping feature complete FSD would happen by the end of 2019, but he was too optimistic about that.
After he said it would be done in 2016, then end of 2017, then 2018, etc... It's always "3 months maybe, 6 months for sure" (actual Elon quote) or "sooner than anyone thinks" (also an Elon quote about FSD from few years ago).
Elon doesn't think in the SAE terms. Tesla has always defied convention with AP and "FSD." They don't need to fit their ideas into another group's box.
Ah yes, the Texas sharpshooter method, keep redefining the target to be able to claim hitting it. When Elon said during AP1 reveal that the car will find me anywhere on the property, it meant as long as it's no more than 40 feet away in a straight line from where the car starts, and while I hold a dead man's switch. He just "forgot" to qualify that, right. When Elon boasted how P85D was a 700hp car, he mean Elon's custom definition hp, because after few years Tesla published actual hp (as defined by standard) and it turned out Elon's 691hp = 463 actual hp, like the rest fo the world defines it. Now you're saying "To Elon Level 5 means something completely different". Ok, if by Level 5 Elon means whatever the state of the car will be in few months, of course he's guaranteed to meet it, by definition. Using your logic, why don't we just agree that all Tesla's are at Elon's Level 11 autonomy right now, which we can if we don't use any standardized definitions, sound good to you? However, drop all the level stuff, when is FSD going to do everything that Elon sold in 2016 (read the above screenshot again) - no Levels, just plain text from Tesla FSD description.
