I had another idea about it and I'm wondering what other people think: by buying Twitter/X, Musk has waded deeply into the culture war, and we see on HN plenty of people who just can't stand to see his name. It seems a sizable community, could the supposed downward trend in the industry simply be a lot of refusal to buy Teslas? It would not necessarily reflect directly in Tesla sales because reduced demand for Teslas could be made up on margin by other undecided EV brand buyers seeing more availablity of Teslas and switching because they feel Tesla is an upgrade. In a like manner, some of the former Tesla buyers might not be willing to downgrade from a Tesla, so they hang on to their car longer, get a hybrid, etc.
