I don't think so. I think it will mean more write offs. These castings replace current pressed panels, so anything in that area will now mean a new body shell -which realistically will mean a written off vehicle - where repairs would currently be an option.

I think this is manufacturing optimisation at the cost of overall life optimisation, like the epoxy-encased batteries which are less recyclable than the previous generation.

Other commenters have pointed it out in different threads, but these castings won't replace the panels. They will replace the current chassis.

I'm aware of that. But using those terms is somewhat misleading - modern vehicles use a monocoque chassis, and these castings will be in areas which are routinely damaged in collisions where panels can currently be replaced/repaired by any competent bodyshop. You can usually buy such sections individually, unpick the originals and replace with new ones, returning the vehicle to as-new condition - even when you're a DIY mechanic with suitable equipment.

That won't be the case with castings, and even less so with Tesla given their approach to third-party repairs.
