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
For those that have had enough of the Elon Musk worship online.
No flaming, baiting, etc. This community is intended for those opposed to the influx of Elon Musk-related advertising online. Coming here to defend Musk or his companies will not get you banned, but it likely will result in downvotes. Please use the reporting feature if you see a rule violation.
Opinions from all sides of the political spectrum are welcome here. However, we kindly ask that off-topic political discussion be kept to a minimum, so as to focus on the goal of this sub. This community is minimally moderated, so discussion and the power of upvotes/downvotes are allowed, provided lemmy.world rules are not broken.
Post links to instances of obvious Elon Musk fanboy brigading in default subreddits, lemmy/kbin communities/instances, astroturfing from Tesla/SpaceX/etc., or any articles critical of Musk, his ideas, unrealistic promises and timelines, or the working conditions at his companies.

Sub 10 micron. Jfc, this idiot doesn't have a clue about auto manufacturing. Even the most precise parts of auto manufacture don't require "sub 10 micron" tolerances. Engine bearing journals are about the most crucial fit in a car and they are generally on the order of 50 microns. Electric cars can use even wider margins because they mostly use ball and roller bearings instead of babbit bearings.
But... Since were talking about the body panels on the worlds dumbest truck the point is even more moot. John Delorian was stamping out stainless panels in the 80s on a shoe string budget,
but the worlds richest dipshit wants to make it out to be the automotive equivilant to brain surgery.
10 micron refers to the decimal places in machining.
Having a tolerance of .01 mm isn’t crazy on some parts.
Molds for injection molding for example
