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'm not a mechanical engineer but I'm happy this story was posted here so that I can ask questions!!

What are typical tolerances on large steel and/or aluminum and/or plastic parts on car sized panels? As a non-mech-e I'm not instinctively seeing the problem here.

EDIT: Oh wait a sec... I just made a hobby PCB with 130um tolerances. (5mil or 0.13mm). Huh... Single digit micron tolerance is absurd.

It’s not absurd for drive components with slip, or press fit on small diameter, though although those go looser the bigger the diameter. If going by the ISO or ANSI tables. But doubt the parts are small enough to warrant that
