Rivian, for one, spends over twice as much to build a car than they end up selling it for. The disparity is larger than Tesla's has ever been, as I recall, and there's every reason to believe they can't simply scale their way out of it. They have to figure out how to fundamentally build the car using less than half the effort and material it takes today.
