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 f…

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.

Earlier quoted context omitted.

The RWD model was only for sale briefly after launch. I don't know why you would ever want a pure RWD electric truck

With the weight of the batteries in back it might be fine. The issue with RWD trucks with traditional drivetrains is the lack of traction owing to all of the weight being over the non-drive wheels. Driving my F-150 in the snow or rain was always dicey because of this. That being said I wouldn't touch a Tesla with a barge pole for reasons numerous.

Batteries and the engine. The engine sits in line with the wheels rather than being under the hood of the car. That puts all the weight right next to the driving tires.

But agree, cybertruck is a really silly purchase for numerous reasons. The only reason you'd buy it is to signal your support for Elon. It's a very bad vehicle.

Cheap ass studs, not surprised. Don’t tow with a cybertruck either, you can literally total it by ripping the frame out with the hitch. It’s the most poorly engineered “truck” there is. Can’t tow. Can’t haul (stupid bed design). It’s just a glorified pavement machine.

Wow, that would be wild to see. Where can I see a Cybertruck owner "literally ripping the frame out with the hitch?"

Watch WhistlinDiesel cybertruck video.

What sort of engineering standards are these Cybertrucks built to? Oh, very rigorous engineering standards. The wheels aren't supposed to fall off for a start.

It looks like they were designed by a disruptive startup unburdened by the history and experience of designing and building cars.

It was super delayed and I think that's because they couldn't execute in all the ways they promised they would. The final product is very rushed and pretty different from the initial promises. I think they got into "Let's just ship SOMETHING" mode as the delays were getting insane.

The same engineering standards as other Teslas are.

Meanwhile, about 63% of Tesla Model Ys failed their first mandatory inspection in Finland. The Tesla Model 3 did a bit better at 59% of cars failing their first inspection for the same model year. However, they're faring a lot worse than the third worst car, the Dacia Duster, at 23%, or other EVs like the Volkswagen ID.4 at 6%.

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