It's worth noting that crack formation is affected by more than just the design - variation in material and manufacturing steps could also contribute. A more robust design can potentially compensate for material or process variability, but those variables were likely not known nor knowable during the design stage. We should not boo companies for acknowledging and correcting issues which may not have been reasonably foreseeable.

Yes, absolutely. The Cybertruck was indeed the first of its kind to have 4 wheels attached to its structure. No car company before Tesla had ever done this before and as such, it was impossible to gauge what kind of material was best suited to handle stress over long period of time.

It's just ridiculous.

> those variables were likely not known nor knowable during the design stage.

But they could have included an error factor in the designing process. I thought this was standard for manufacturing. And they could have done more robust testing which, again, I thought was pretty standard for manufacturing.

I would have thought that material and process variability would be one of the primary design constraints in physical engineering?
