BYD sells several times more different EV models in twice as many countries, yet it only totals 38% more EV units than Tesla (2025). What puts them in the top 10 is their non-EV sales, which Tesla doesn't do at all.
Cybertruck is a flop, no argument there.
The reason Tesla hasn't scaled further is that a few years ago they pivoted in strategy and are no longer heavily pursuing the consumer market with new models for personal ownership. For better or worse they are all in on autonomous fleet vehicles and Optimus. The pivot was probably a few years too early. Many think it'll never work and I'm sure you're among them, but time will tell.
