Tesla is facing issues with the bare metal construction of the Cybertruck, which Elon Musk warned was as tricky to do as making Lego bricks

Wait, I thought he was just bullshitting his fans with that. He's actually serious? XD

Also, I don't understand what this has to do with bare metal construction of the Cybertruck and why that should present exceptional difficulties. DeLorean figured out how to make bare metal cars more than forty years ago, so it can't be that hard.

DeLorean also didn't use flat panels on the body. Though it might look like it at first glance, none of the DeLorean panels were flat, they all had a slight curve.

All metal panels are gonna flex a bit in the changing temperatures.

That's an idea I would have supported when I was taking high school physics. My astronomy calculations I put to the nearest centimetre (something like 20 significant digits sometimes) for no good reason. Just writing down all the numbers from the calculator.

Then I took engineering and grew out of it. Sure some crucial parts need very tight tolerancing, but you also have to have it relative to the size of the part. And if your design is bad, better tolerancing isn't going to save you from stuff like the steering wheel popping out.

No amount of accuracy is going to fix the ugly of that thing.

It'd look better. Even with the struts out.

I know it's supposed to make them sound good and might indeed be meant for leaking, but all I can think of is the demands on quality assurance and risks of failures down the road if such precision is paramount for the operation of the vehicle and assumed by the teams building it.

So give me a less finicky vehicle, please, and leave that precision for devices not subject to highly varying road conditions at very high speeds and housing people.

Every time I see it I can't get past how hideous it looks. I just don't get it...who's the target demo for this thing? They've already been beaten to market by non-absurd looking trucks, how big could their market actually be?

High accuracy, low precision.

Isn't the metal body going to expand depending on the temperature? This is so unhinged.

Machining parts to that precision would exponentially increase the cost of the individual parts. This is something that will never ever ever happen and I'd be willing to bet my entire fortune on it. No Cybertruck will ever be mass produced with all it's components within 10 microns of tolerance. Elon might roll one off the line like that to prove that it can be done, but nobody other than his billionaire buddies would be able to afford one.

Kind of wish we would just get away from cars. I'm in a car centric neighborhood and miss the days of when I didn't live in one.

There are companies making bricks in much better quality than LEGO, and they are cheaper than LEGO. What kind of a margin is this supposed to be?

[–] [email protected] 26 points 10 months ago (5 children)

cheaper than lego

I'm listening. Please do share.
