Was fun looking back, but I don't recommend the Cybertruck for this mission. I would say stick to your local trails with 6 or lower to avoid damage.

Moonroof?

Should have turned off rear wheel steer, would have likely saved the rear axle/rack.

That assumes the rack generates more force than the tie rods can handle. Seems like a poor design decision if so.
External forces acting on the tie rods via the wheels can be higher than the rack's force. The cracked front rack seems like a potential example of this if the rack's travel was exceeded and hit the mechanical limit.

Doesn’t the wheel being turned potentially increase the amount of stress being placed on the tie rod and hence the rack by those external forces?

Maybe? My thinking is that if you trap the wheel then steer, the rack shouldn't be able to bend the tie rod. However, if you drive into a wedge, the squeeze could overload them.
Then there is the backdrive force factor...
Even if rear steer is disabled, the motor should still be working to center the rack.

Moonroof?

Moonroof cracks due to body flex.

We had it off after the first issue, still was damaged 2 more times. Having any ability to pivot creates weak point.

With a traditional R&P steering rack, driver can tell when the wheel is on the side of something, vs the drive by wire, the rack gives ist 100% I'm guessing all the time with no driver feedback. That said Tie rods are common failure point on the Rubicon, so either way would have happened. Could it be better yes, b ut for 99.9% of CT owners will never be an issue.

interesting - do you think that some of your damage might have been prevented with haptic feedback that is missing because of steer by wire? that does make a lot of sense! one of the (very few) downsides of robotic surgery is the lack of haptic feedback which can increase the risk of tissue injury because of tearing. its why the newer generations of robots have it.

The system does have force feedback, but maybe it needs more...

Surprising given how torsionally rigid they claimed the body was.

The more I see/hear the more I think they should have gone with a traditional body on frame construction.

Happy Friday, folks!
Hope you enjoy the carnage report video, let me know if you have any questions, comments or want to talk trash.

This was probably the best video you’ve done. Did a good job highlighting areas Tesla could consider for development and the reality of this kind of offroad. Allows people to understand the strengths and the weaknesses of the vehicle.

I do wonder: surely someone must have tested the Rubicon in a stock F-150?

Actually this is another somewhat worrying result. It’s all but impossible to avoid any flex in offroad conditions. The fact that could crack the roof does raise some concern for use in work environments.
