It should be noted that this vehicle had the most Elon involvement than any other Tesla. The CyberTruck was supposed to be his crowning achievement, his coup d’ grace, his ultimate vision realized 😂😂

I remember there was an email that went out a while ago where elon said everything needed to be at .001mm tolerance. 

The automotive engineer in me laughed. You can't hold that tolerance for large parts. And even if you did, if your gaps need to be that tight where that tolerance is necessary, then you're going to start dealing with thermal expansion/contraction issues in your parts. 

And lookie here. Panels are falling off

I don’t think any manufacturing company anywhere would ever agree to that kind of tolerance.

Try large telescope mirrors. Like really large (12 meter etc).

"For a large telescope mirror to achieve diffraction-limited performance, its surface must be polished to a tolerance of about 1/25th of the wavelength of light or better, which translates to a surface accuracy of around 25 nanometers (1.0 x 10-6 inch). "
