I've seen rumours here and there (albeit nothing particularly reliable) that the Cybertruck might be a platform used to learn about this design/manufacturing approach. It's hard because it's hard, but the Cybertruck is how they learn how to make it easier.
The thinking being, of course, that if/when they get it nailed, they've potentially got an advantage to leverage over other manufacturers for future cars such as the Model 2.
Only time will tell whether this is the case, and whether it worked.
This is nonsensical, the Cybertruck is a terrible platform that had serious Chassis design issues that any other automaker would have killed the design over, but because Musk's ego is too big, there was never an option to say "we need to go back to the drawing board".
