Carbon fibre is incredibly expensive to manufacture. It requires a lot of manual part manipulation and yields can be poor.

BMW made a big bet that batteries would remain expensive and weight would matter for EVs. i3 and i8 were studies in scaling up structural carbon fibre mass production based on that bet that failed pretty badly.

Structural batteries are already a thing. Carbon fibre won't be the housing without a bunch of innovations.
