This "they will sell all vehicles they make take is moronic" is moronic.
First, EV truck is a niche product, second Cybertruck is a niche of that niche, third reading between the lines of Tesla statements about CT it seems that the steel body manufacturing will be very hard to scale efficiently, fourth the cost of making the "exoskeleton" fit for purpose probably means that the CT is not particularly profitable, fifth battery supply is still a factor and CT batteries could be going in to more profitable products.
So, difficult to scale, not worth the effort anyway, so low volume production at high prices to a willing but limited fanbase happy to wait.
It is a fun product but what the market will buy in huge volume is a cheaper practical EV and BYD aren't making Cybertrucks.
