Lars Moravy in new interview on why the @Tesla Model S and Model X were discontinued: "Every 5 years or so Euro NCAP updates their protocols. Looking forward, they are getting more stringent. Some of the IIHS stuff. We want to make the safety cars on the road, and that means always making structural updates. We were at the point where this platform, like it was never designed for the small overlap and the offset cases that exist now on Europe NCAP and IIHS. We made bandaids along the way to make sure it was being safe in those positions, but it was just like man it's going to be a massive overhaul. At the same time, going back to the room it was like we were talking about Optimus and like where do we put Optimus and it was like well we got to spend you know however many hundreds of millions of dollars to redo this in this factory, but we also need a pilot factory for Optimus. And it just kind of was like serendipitous. I think that the two things went hand in hand. You said who was the first one to bring it up. The future is autonomous. These cars were the first ones we designed. They're the least ready for that, you know, world. So, we got to move forward." Sounds like it just wasn't worth the investment, since it was likely going to cost several hundreds of millions to retool and redesign, and maybe even more to build a pilot Optimus factory somewhere else, when it would just make more sense to use the S/X space in the Fremont factory.
