You're forgetting a key growth driver for all ev: Europe, some US states and non euro countries are set to ban ice vehicles from 2035 which will have tremendous consequences to the traditional auto market, fuel distribution and cost, repairs, etc.
As of this month, Tesla already has the best selling vehicle in Europe, not just ev. While the competition is coming, it's still far behind. Chinese makers will likely be banned from export to the alliance countries when Xi decides to invade Taiwan; the US can't figure out how to make cars anymore, let alone EV; Korea and Europe are the strongest competition but they're still working out production and supply kinks, giving Tesla at least a 5 years lead.
