I think there will be a downtrend coming. A massive chunk of those sales come from China. If you know anything about China, they tend to take a good idea, reverse engineer it, and make a cheaper version of their own, sometimes even better functionally.
They have already done this with EV's, with cars like BYD dominating, set to surpass Tesla any day now. Further, there's a lot of political sentiment against Tesla. Nationalism will always win over, and ultimately, Tesla will phase out, pretty slowly I imagine, but after years of declining sales.
This is not just a blind prediction, but based on countless examples over the years falling for the exact same fate. But for Elon it's even more sensitive, because he has to constantly balance this idea of 'free speech' with marketing to China, which demands the exact opposite.
All it takes is a little outrage by some Chinese netizens about something some random guy said on Twitter, and suddenly Teslas are getting their windows smashed in across China and boycotted.
Never do business with China XD
