I've been doing PCB-board design recently. Here's the manufactuering specs: https://www.digikey.com/en/resources/dkred
So that's 0.13mm tolerances to my printed-circuit board. Or 130 microns.
Current leading theory is that Elon Musk is such an ignorant dumbass that he doesn't know the difference between mils and microns, despite running a car company / manufacturing firm. Give that a thought. Even then, 10-mils tolerance is near this PCB design, an object that's only a few inches in size. Cars are much larger and normally should be built to much wider tolerances than a fucking PCB board.
If he said <10 mils, I'd might have bought the explanation that Elon actually meant millimetres. Micron is a very specific metric-based unit which to Elon might have been trying to use like a buzzword.
The moral of the story is don't say stupid engineering stuff if you don't want engineers to laugh at you.
And 10 microns at what temperature? Because on something the size of a car, made of mixed materials, thermal expansion of less than a degree is going to blow that figure.
They couldn't apply paint to a tolerance of 10microns.
Ten mils is .010" or .25mm if I'm not crazy.
It's a very standard tolerance for aircraft parts.
Yeah and that wouldn't be too bad either... still expensive but not completely unrealistic for ALL parts of a car.
Kinda unreasonable for the number of cast parts most cars use, but for machined surfaces it shouldn't be too bad.
It's almost like Elon Musk is a complete fucking moron and not an Engineer. The wanker has never actually designed a thing in his life. He just tells other people to design something, or buys an existing company, then struts around like he thinks he's the smartest thing around.
He was fired for being incompetent. Only got rich because rich daddy and because he got lucky with stocks
I recently listened to a podcast about musk which was more on the anti side. The podcast had some parts about spacex and musks own work ethics, which told more of a story that he actually has some insights and knowledge and was a insane workoholic. Which shifted my perception of him. He isn't dumb, he is a really good conman.
