Elon musk might know a lot about manufacturing space ships and electric cars (edit: that’s a big might).

Well he this about Cybertruck:

All parts for this vehicle, whether internal or from suppliers, need to be designed and built to sub 10 micron accuracy. That means all part dimensions need to be to the third decimal place in millimeters and tolerances need to be specified in single digit microns. If LEGO and soda cans, which are very low cost, can do this, so can we.

What’s fault tolerance?
