[this video] (octopump) It's not that heat pumps won't work, it's about pump technology. This is actually the thermal management system, used for both heating and cooling. Sandy generally has great commentary on the auto industry. He's quite genuine Every auto company misleads, at least Tesla is being a leader The point about accident rates is in context of unwitting beta testers. There are many drivers on the road, many of who make the road unsafer. That fact should also be considered when discussing road safety. If FSD beta is better on average, then the roads are getting stepwise safer.

> That's a function of battery size. The maximum battery size of the current Kona, Niro, and Soul is 64 kWh. Batteries cost money. The Kona, Niro, and Soul are all less expensive than the top end Teslas. The Model 3 LR battery size is 75 kWh. Are you telling me a 9 kWh difference say ~15% is the sole reason for an almost 25% increase in range? If it is only a matter of the battery size, the range would be linear. It is a function of battery size, total mass, and efficiency. A more or less efficient heat pump is absolutely a defining part of this equation, especially in the cold, as the press release you linked stated. It is why the longer, wider, and taller Model Y has only slightly less ran

- Mega Castings, casting have been used before, but never at the size Tesla does. Tesla has costume co-designed machines and they developed their own alloy to make it work. See: [LINK] - Structural Battery Cell (Packs are structural in some cars, not cells) Eventually these two things together will basically be the main part of the car. This is nothing like anybody else does it: [LINK] - Fully integrated heating/cooling system 'Octovalve' ( [this video] ) - Unifying chips to central computer - Stainless Steel Exoskeleton You can see a full breakdown of a last year Model Y here (same guy that did this interview with Elon, was very critical during Model 3 and impressed now): [LINK] That is of cours
