Elon has made some VERY aggressive design decisions.

• Your car likely has as a seat made by Company A, Environmental Controls by Company B, Transmission by Company C, Infotainment by Company D, Enginine controller by Company E -et. ad nausium. Firmware updates require "buy in" from each component the firmware touches, which translates to poor, if ever SW firmware upgrades.

• Everything in a Tesla, is made by and for Tesla. Firmware updates are regular, meaningful, and improve as time goes by

• Your car likely has large sections that are bolted, welded, or otherwise permanently attached. These pieces are expensive to make, repair and maintain.

• Tesla makes HUGE molds, where a single cast part can replace it's comparative component that has up to several hundred process steps built into it.

China is going to have to do the same sort of thing - which means that the way Detroit and other cars have been building cars for decades; will fundamentally change, at the grassroots level.

Doesn't matter if this is ICE or EV; these are fundamental design and assembly changes.
