I think their strategy is to charge the highest prices they can, early adopters pay up, demand gets exhausted and they have to keep the illusion alive that supply is the growth constraint, not demand. Demand falling is a death knell for them so that is one thing they absolutely must avoid at all costs.
They want people to believe that the demand is a foregone conclusion and they need to build more factories to satisfy it. But clearly they are trying to maximize the profit. Of course they would like to lower their costs in pursuit of that but it’s not to charge the least they can, otherwise they’d have led with a compact EV instead of an $80k luxury sedan.
