I would like to remind everyone that this car has technically been delayed for a couple of years. They've been working on the new pack/cooling system since mid-2019 and the leaked reports for that, as well as the interior refresh were all around the same time.
So while we are only 1-2 months away from deliveries - bear in mind that Tesla officially managed to keep quiet for almost 2+ years. Elon screwed up in Q1, I still believe that he believed that it was ready to go and they were in fact getting ramped for production/deliveries (which is why they had the manufacturing team called back in). I also still believe something went wrong that they don't want to talk about publicly (though Elon pretty much told you on the earnings call).
With all of that said - I've gone from being extremely pissed to at peace (7 stages of Tesla grief) - but this is an emerging technology and none of us truly know just how unique the components are in these new vehicles, though it certainly sounds like a complete overhaul of internals. Because of this there are going to be hiccups and maybe an unexpected edge case that occurs.
I get everyone is pissed about communication and so was I but Elon addressed the delay head-on during the earnings call and already updated the timelines to "probably next month (May)" delivery slow start with a ramp in Q3. What more do you all want at this point?
