I'm a bit conflicted about this letter. I like the general tone and I'm completely comfortable with the 691HP discussion which I think is the clearest and cleanest claim and where I most believe Tesla has mismanaged their message. I'm less comfortable with the 0-60 discussion because as a performance car enthusiast I know all about the 1 second rollout and I've seen many cars where owners never ever manage to hit the advertised 0-60 times even with rollout. In my mind including this in the letter weakens it because this issue is much more easily explained by Tesla. The part of the letter angling for free ludicrous upgrades and explaining to Tesla why it would be a PR benefit to them really trouble me. It supports some of the nasty comments upthread and is the only part of the letter that makes me uncomfortable signing it. The explanation of why it would be good PR is particularly condescending and troubling, IMO. I also 100% agree with neroden that the change in policy related to Ranger service is a worse change and I'm always surprised it gets so much less attention here, but I guess there is no point cluttering up this thread with another distraction.
