He addressed this. Elon "doesn’t deliver everything he talks about".

His point is that Elon may promise more than he delivers, but he has still delivered on quite a lot.

No, a self driving car can be either supervised or unsupervised.

I'm required to supervise my car while it drives me to work, but it is by definition fully self driving, controlling all aspects of the vehicle while I sit with hands off the wheel watching

Let's not move the goalposts. He promised unsupervised FSD for 2019 and he promised level 5 autonomy for 2020, they're still at level 2 autonomy.

Per https://motherfrunker.ca/fsd/

[2017] The sensor hardware and compute power required for at least level 4 to level 5 autonomy has been in every Tesla produced since October of last year.

[2017] I think that [you will be able to fall asleep in a Tesla] is about two years

[2018] Probably technically be able to [self deliver Teslas to customers doors] in about a year then its up to the regulators

[2019] We expect to be feature complete in self driving this year, and we expect to be confident enough from our standpoint to say that we think people do not need to touch the wheel and can look out the window sometime probably around the second quarter of next year.

[2020] Robotaxis release/deployment... Functionality still looking good for this year. Regulatory approval is the big unknown

[2020] I am extremely confident that level five or essentially complete autonomy will happen, and I think, will happen very quickly, I think at Tesla, I feel like we are very close to level five autonomy. I think—I remain confident that we will have the basic functionality for level five autonomy complete this year, There are no fundamental challenges remaining.

[2020] I'm extremely confident that Tesla will have level five next year, extremely confident, 100%

[2021] FSD will be capable of Level 5 autonomy by the end of 2021
