I don't know if the comment is being deceptive. I'd say the commenter is at least confused. And I did point out why.
The confusing thing is Elon and Tesla both share a lot of information about timelines for prototype technology. "In six months it will do x" kind of statements.
The two faces you are confused by have names. The first face is prototype technology. The second face is shipping cars that we regular consumers can drive.
All the confusion can be cleared up by simply asking yourself, for each statement, which of these are they talking about in the current context?
Keeping in mind that both prototypes and current shipping cars can appear sometimes in the same context, such as that web page. It takes a bit of discernment and careful reading.
If you (general you, not you in particular) are predisposed to assume Elon is a massively deceptive fraudster who is constantly lying and hyping, then it's convenient to overlook that these two faces have a perfectly logical division that fits reality and makes everything consistent.
That is what a lot of people do. They overlook the fact that both Elon and Tesla need to lay out their vision for what is coming in the future. When Elon and Tesla talk about this stuff, they often need to talk about prototype technology. They often make it clear when they are doing this. I mean, look at the web page. The words are there. It does say "future" and "current cars don't have this blah blah" (although Elon in his interviews doesn't do as good of a job, it's often obvious with a moment's thought that he's talking about prototypes, to those of us who are familiar with the fact that there will be a multi-year regulatory process before whatever feature he mentions will come out).
I guess the problem is that technology is complex. Self driving cars are another level of complex because of the context in which they are situated, amongst other cars and drivers who need to learn to deal with the new robo drivers. Socially complex. Legally complex. Complex environments. Complex timelines. Complex rollouts. Complex technology evolution. You don't just flip a switch with this stuff and turn it on one day, because of the education aspects where other drivers are going to be in the picture. People aren't used to this level of complexity. Elon can't spell all this stuff out in every answer to every interview question. It's up to you to understand this.
Average drivers of a Tesla don't need to understand all the complexity. They just need to understand that the current system requires them to be attentive and ready to take over at any time. Tesla makes this abundantly clear in many ways, including on the web site, during the sales process, during delivery, and with active messaging and interventions while driving if the driver does not get it.
