As a late 2016 buyer I was greatly influenced by the statement that EAP was expected to "complete validation" in December, just a few weeks after I committed to the purchase. I inferred from that that all the prerequisite steps - designing the system, writing the code, unit and system test - had already been completed, leaving only "validation", whatever that may be.
Was that said explicitly? No. Was it a reasonable inference? I believe yes.
Before attacking my reading comprehension skills, as seems to be fashionable here, imagine this husband-wife dialog:
-------------------
"Honey, we're going to be late for the show!"
"Stop worrying , I'll be down as soon as I get my earrings on!"
Ah, he thinks to himself. Putting on the earrings is the last thing she does. We'll be on our way in a minute.
Hah, she thinks to herself, rising from the bed. It's a good thing he didn't ask if I've showered, dressed, and done my makeup!
-----------------------
Apologies for the gender stereotyped role play; it was the first thing that came to mind.
My point is: I relied on Tesla to describe the situation accurately before requiring me to commit, rather than use language whose effect, and possibly intent, was to create a false impression about the actual status of these future deliverables.
