I guess that is the key argument, and it makes sense: why the **** would Tesla give MT a ringer to test, knowing that customers are already confused and disappointed, if they weren't going to satisfy the customers really soon.
I hope you are correct.
Assuming you are, the question remains, though: Why does Tesla continue to have to first confuse and disappoint its customers before eventually delivering?
If they eventually deliver the software that will allow the P90D with Ludicrous to complete the 10.9 second quarter, it will meet the spec it was sold as having, SEVERAL MONTHS AFTER PEOPLE STARTED TAKING DELIVERY OF THE CAR. Why? This is exactly analagous to what Tesla did with respect to the P85Ds and Torque Sleep. The cars were delivered without any Torque Sleep capabilities, were not getting close to the expected efficiency, and no one had any idea why for about a month.
I understand that Tesla, perhaps because of Musk, may be overly optimistic with respect to timelines. I understand the need to sell cars. But to keep conducting business this way is wrong, and its going to hurt the company.
I know for certain that as a P85D owner, I would have been a lot happier if, when I took delivery, someone said, "Oh, and by the way, Torque Sleep isn't active yet, but it should be in a month or two." I can't imagine very many P85D buyers would have refused delivery over that. Similarly, I expect P90D with Ludicrous buyers would have been happier with an explanation that their cars are not yet quite capable of achieving a 10.9 second quarter mile time, but soon will be, rather than having to have found this out on their own, worrying for a few months about whether or not the car would ever achieve the 10.9 second quarter.
I really think that someone needs to get the point through to Tesla and Musk that for the long-term good of the company, honesty really is the best policy.
