Bonnie, no argument with this, since using the word "some" indicates that you realize that some people were mis-informed. Some were not accidentally mis-informed. Some demo'd AP1 cars, and were told by sales directly that parity would be achieved in December 2016. This was reported numerous times here, and in other forums. I agree, there is no need to re-argue semantics over 'expected', but me and others take it from a manufacturer of consumer products as an expectation, a commitment, that is based on inside knowledge.
Let's be honest, too. You are a Tesla alumni, an insider as it were, who has been around for a long time in the Tesla world. You understand EM's use of hedge words, his penchant to be deliberately abstruse, and some of the exaggerated promises that are passed of as "that's just Tesla". Sorry, I believe that EM and Tesla deliberately misled, and continue to mislead owners and prospective buyers. Thus far, they seemingly have gotten a pass on it. It's not right.
