I wouldn't romanticize it that much.
Tesla used to be: Unmatched software(+), unmatched electronics(+), Save the planet(+), great subsidies(+), electric car that doesn't look weird(+), USA and Startups and the future(+), unmatched acceleration(+), low built quality(-), Shitty driving dynamics(-)
Now alternatives are pretty good, so still Unmatched software(+) but the difference is not that big and the rest doesn't look good. No longer saving the planet because you don't save the planet with fascists, USA is no longer cool(hostile and clown-like), tech guys are no longer cool(greedy and sleazy and meddle with politics instead of doing cool shit), the design is dated and boring now and there are many alternatives doing much better in many other characteristics.
So Tesla still sells very well when the price is right, match the new situation and it sells. Tasla sells like hot cakes in Turkey for example because they introduced a version specifically for the Turkish regulations and that particular configuration is taxed just %10 when the cheapest petrol cars are taxed %80. AFAIK Tesla keeps selling well in Norway too.
