It may or may not be the car for you ( I am not debating that), nor trying to make light of it. One thing I would point out is, The people manning the text / emails probably answer that specific question a hundred times a day or more, as people constantly reach out about their ETAs.
Multiply all the "My Estimated Delivery date did XXX" here, with all the people who are not on this website and doing the same thing, and I would imagine there is likely some frustration on their part at constantly answering that exact question when they dont have any more information than the customer already has.
That doesnt excuse lack of politeness, but it does EXPLAIN it. You likely wouldnt have liked the answer much whether they put pleasentries in there or not, and for each person who wants to have some pleasentries in there, there are others who are "get to the point".
I dont work for tesla or nor have any specific knowledge of their inner workings, however I have, in my own career, either performed, or managed, customer service roles for my entire career (almost 40 years now). Some things are the same no matter what industry the support is in, and one of those things is the very human nature to get annoyed at being asked the same question, that you can do nothing about, 100 times a day.
