What I meant is that Elon has set a fairly un-achievable standard, as the sheet metal parts he is talking about will grow and shrink by more than that depending on weather. Additionaly, the small parts can be machined to that tolerance, but only by a skilled machinist and not at assembly line levels.

Besides just thermal expansion, which will totally happen by driving on the road, the rotation of the motors and the use of brakes.

It will also flex as it hits bumps and takes turns.

And these will be different metals. With different thicknesses which will expand and contract at different rates.
