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.

I thought this was standard for manufacturing. And they could have done more robust testing which, again, I thought was pretty standard for manufacturing.
- jjk166 5mo ago> But they could have included an error factor in the designing process. They almost certainly did. But that error factor is a guess based on limited testing. You never know your true variability until you're building at scale. Waterfall development doesn't work in the real world any better than it does in software.
- p-o 5mo agoYes, 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.
- jjk166 5mo agoTell me you're not an engineer without saying you're not an engineer.
- dghlsakjg 5mo agoI would have thought that material and process variability would be one of the primary design constraints in physical engineering?
- jjk166 5mo agoAnd if engineers were all knowing that is how it would work. Unfortunately the real world is complex and there are limits to how variability can be constrained.
- kennywinker 5mo ago> We should not boo companies for acknowledging and correcting issues Nobody is booing the recall, they’re booing a company that makes the bad choices that lead to recalls like this. E.g. doorhandleless firetrap trashcan car with sharp corners and a high front for extra pedestrian-murder.
