but you can kinda see my point....with the amount of pre-orders, they will most definitely be buying in bulk on a lot of these parts, thus bringing the overall price down.
I suppose all of this really depends on "Part 2" of the reveal. Will they "package" these like other carmakers? Will you still be able to largely order a la carte? At this point, there's a lot about this that ELON doesn't even know yet.
But we're all still excited to find out!
