Tesla is facing issues with the bare metal construction of the Cybertruck, which Elon Musk warned was as tricky to do as making Lego bricks
I guess they could do like Nissan did with the GTR’s engine: climate controlled assembly bay, temperature check on the parts etc…
But I mean, they did it only for the engine which is relatively small
It’s not even about that. You absolutely don’t need those tolerances for a cup holder. An assembly line will fuck it up regardless. You use tolerances like that when needed - in jet engines or turbines. Insisting on those numbers on a car is plain stupid - it isn’t better (other than the ego boosting “my car has high tolerances where nobody cares”) than just doing it like every other manufacturer does it. It’s a waste of money plain and simple.
