If your're such a fucken genius why don't you just make the cars out of lego and beer cans then? Ever think of that ya fucken knob?

Given that teslas have notoriously bad tolerances, like gaps on the order of millimeters, ya might want to fix the cause of that first lol.

This is how "entrepreneurs" "innovate". They just say they want something and everybody else tries to work around the roadblocks the CEO probably put in place that make achieving the goal way harder than necessary.

I like how he explains what a micron is as if the people who actually build things at Tesla don't know

and honestly a little jankiness will just contribute to the PS1 aesthetic, he should want to lean into it for meme marketing purposes

It really does take a genius and visionary to sit back and say "Hey, guys, let's make this, but with as small an error as I can imagine. Don't like, assess how precise stuff needs to be or consider any of that. Just make it all like really, unreasonably well, okay?"

I'm sure the engineers are blown away by that big mind, what a privilege. It reads like an excuse to blame the engineers when the truck inevitably sucks because they didn't follow his perfect design.

I used to work for a company that made stamping dies for aluminum cans, and some of those dies had tolerances close to .0004", because the aluminum is very thin and could crack and tear if the dies were not made precisely. The cans themselves are not that precise, they just need to hold beer without exploding. I can't speak to Legos, but cars absolutely do not need this kind of precision, not even in the bearings. And especially not in the sheet metal body panels.

Critical support for demanding sub-human hair tolerances for the panels of that shitbox. I'm sure you will get it done for a bargain.

Teslas, famous for their tight tolerances.

Listen everyone: just make the parts perfect. All of them. You know how it hasn't been perfect so far? Yeah that sucks, do it perfectly instead.

Five hours later, in another email: “Sorry everybody I was super high when I sent that last one your way.”

Bro I wish I had rifles with that kind of tolerance

I've used waterjet, CNC, and EDM parts. The waterjets typically give me ~100 micron accuracy, CNC ~20 micron and EDM ~10 micron.

"All parts of the vehicle"

precision predicates balls

For a super smart inspirational genius, he sure is doing the usual terrible corporate boss routine.

”Here's a bullshit goal I want you to meet all of a sudden. How are you going to do it? That's your problem, not mine.”

Email? He doesn't send down dictates via Xeet now?

Make the tolerances too tight and the body parts will interact with each other in unfortunate ways - shell gets too hot, metal expands, and you can't open or close the doors. Window glass will crack etc.

Watch these fucking life-size HotWheels fly apart when it gets too cold or too hot.

Precision predicates perfectionism

Perfectionism is seen as a counterproductive and bad thing most of the time. Someone should tell King Bazinga that, if only there was someone around him that wasn't afraid for their job.

yea nah. I doubt anything outside of the electronics requires that tolerance. Including any of the bearings. The finest grade of sand is about 62 microns. LEGO and soda cans do not adhere to those tolerances. 100 microns maybe.

I must have confused the cybertruck with one of my rocket engines.

Here's 300 ~~machinists~~ "architects and engineers" telling me off https://www.reddit.com/r/Machinists/comments/15zkpxg/musk_email_to_tesla_today/

Just make it real nice

Someone please get this dork into a locker already

"tolerances need to be specified in single digit microns" technically precludes any tolerance being specified smaller than 1u, so that will be fun for the electronics.

Hahahahahahaha, look, any large production at scale is usually going to be at least .001 inches out of tolerance, especially anything that has to be cut in mass at rate, either that or he is going to be fine if a cnc or water jet guy has to recalibrate his entire machine and probably trash one to two pieces after about the first five years making these things, either that or buy a new one or constantly be replacing parts. Like, it is so rare to ever have anything like that kind of tolerance. It is can be accomplished, for small plastic and light light metals constructions, but large vehicles? It's possible but idk if you will ever really make a profit or be able to produce it quickly.

But I suppose, his wealth rides more on notoriety and finance capital than actual production, but come on man, you just got Tesla in the black (not it wouldn't take like 30 years of unprecedented Chinese level growth to produce manufacturing products that actually pay back the amount of money that was lent out towards to it), why are you fucking with this thing? Everyone knows your cars are shit, nobody cares, you're the Apple of cars, just be happy and make money. These idiots will buy whatever slop you sell, just put it out as fast as possible at the very height of the price-demand curve.

Edit: With how this whole thing was reported and marketed, I really think that Elon is responsible for this one, his fans eat this shit for breakfast.

I can't wait for Teslas workers handling multiple, frequently calibrated high-precision micrometers from different high-end manufacturers and taking multiple measurements and averaging them to get a result.

Because that's how LEGO does it.

Elmo seriously sent that to everyone in the company? When that information was maybe relevant to a handful of people?

tbh I can't debunk any of that, but it wouldn't surprise me if he's tripling the cost of parts that are just going to get smashed into a pole after Full Self-Driving over a crowded crosswalk.

For this to work I'd assume he'd need to invest in gear that can test precision within that range, so nothing will happen

Elon Musk has never written anything worth reading in his whole life
