I didn't say the battery should be sized for your average usage, it should be sized to meet your actual needs.

Er, what?
Yes, how much battery you NEED to get you where you want to go without pushing the limits uncomfortably. Why is this so confusing?

A cold battery will heat up regardless of size eventually. But with current battery technology, charging a cold battery causes lithium plating of the anode. A smaller battery comes up to temperature much more quickly because it has less thermal mass to change temperature.
Either way it being over is better for SP. I don’t think it is being blown off even though the worst outcome is a few million from Elon.
Indeed, the lawsuit is a personal one involving Musk and not Tesla at all. If anything, there is a tiny relationship with SpaceX, since they were to build the proposed rescue vehicle. Still, only Musk could be forced to compensate for libel.
Meanwhile, this will be a jury trial. Selection begins tomorrow, and the judge plans to likely disallow anyone with prejudices against billionaires or prejudices against people who visit or live in Thailand. That procedure may be time consuming.

So, my actual needs are about 3 hours of driving (even in cold weather) without having to worry about having only 2 miles left at the next charging station and without having to wait an extra hour to charge from 95% to 100%.
So, yup the Leaf we had just did not quite make it - although we loved it anyway.
The long range Model 3 is almost adequate - 400 miles of stated range would be good enough. Until then lots of people will not by an EV.

We shouldn’t be talking about average or actual or daily needs. What does actual mean anyway?
It’s a question of what % of your needs are fulfilled. For a small % of needs we can rent. For eg., even 90% is not enough- because that means I’ve to rent 30 days a year. But renting 3 times a year may be ok.
Of course there are 2 car scenarios etc.

My theory is that, bad news regarding Musk gives a boost to shorts and they are emboldened to short more. Reverse happens to longs - who now expect sp to go down on bad news and will wait to buy.

If you consider SEC's action against Elon's going private tweet one tweet from the orange man moves the $40 trillion US stock market whether they are real or fake. SEC is fine with that.
OT: Just lost power on PG&E. Have a powerwall and solar system already installed a week and a half ago but waiting on an inspection by... PG&E

Poll - Q4 M3 production
Mean is about 89k M3s built (incl MIC). This is ~10% up from Q3.

Sooo not relevant.
China ramping.
Q4 deliveries.
Cyber orders.
FSD due.
Battery costs declining.
Model Y sooner than expected.
A heated tweet from Elon made over a year ago is nothing more than white noise.
have to try harder next time, missed it by a few cents
Comment from BizLink Group's quarterly report
2019 Q1
Automotive line: customers affordable car sales to Europe and China, shipments heat up;
And cut production capacity, this quarter's shipments are comparable to the previous quarter. Auto line shipments throughout the quarter are still slightly higher than in the previous quarter.
Automotive harness: Electric vehicle harness escloser as customers continue to expand in Asia and Europe and other markets, as well as customers are scheduled to run the Shanghai plant by the end of the year, the second half of the year
Shipments are expected to be better than in the first half of the year.
2019 Q2
Automotive line: electric vehicle line shipments than the first quarter stronger;
2019 Q3
Car line: the beginning of the season flat, mid-to-end season began to strengthen.
Automotive line, with electric vehicle customers Shanghai plant production capacity gradually started, the medium- and long-term outlook is positive.

"Neko no me"
Cybertruck will be v1.0 of Tesla's new approach to vehicle manufacturing. For the next generation of Tesla manufacturing, let's look at the following, excerpted from US Patent: (US20190217380) MULTI-DIRECTIONAL UNIBODY CASTING MACHINE FOR A VEHICLE FRAME AND ASSOCIATED METHODS
"The present disclosure relates generally to manufacturing a vehicle frame, and more particularly to a multi-directional die casting machine for casting a unibody vehicle frame and associated methods thereof.
"Typically, in the context of vehicle frame manufacturing and the die casting process, multiple die casting machines are each used to cast different components of a vehicle frame.
"There remains a need for an improved die casting machine and associated methods thereof, particularly as related to casting a vehicle frame to reduce work required to achieve a final assembled product.
"The present disclosure describes embodiments of die casting machines and methods thereof that may reduce:
FIG. 1A is an illustration of a multi-directional casting machine for a vehicle frame configured in accordance with an embodiment of the present disclosure
FIG. 2 is an illustration of a multi-directional casting machine for a vehicle frame configured in accordance with another embodiment of the present disclosure.
FIG. 6 is an illustration of an example method of casting a vehicle frame configured in accordance with an embodiment of the present disclosure.
Look for Cyber v2.0 production to commence sometime in 2023 (or shortly after Tri-motor Cybertruck). Tesla is moving forward with their vision for "the machine that builds the machine". That new architechture will manufacture die-cast stainless-steel metal-foam million-mile uni-body cars/trucks in huge volumes, and at an unmatched low per-unit cost.
"Economical. Durable. Intelligent. Connected." Tesla's unbeatable combination of attributes will change the world forever, no going back. Consumers will demand nothing less, indeed some will also insist upon "Fast". WE GOT THIS.
TL;dr Cyber v2.0 is:Stamping | Body | Paint | Die Casting | General Assembly
Cheers!
P.S. If Tesla acquires companies like Havel Metal Foam in Brandenburg, that'll be a tell.

Not sure that's possible, the cold-rolling of stainless steel into sheets changes the crystalline structure (it's a form of steel work-hardening), it hardens and smooths the surface:
Casting is fine if you are creating a primarily load-bearing structure, such as part of the frame, but the extra hardness (scratch and corrosion resistance) is a key physical property for an exoskeleton.
A cast steel surface is also fundamentally rough and cannot normally be a customer facing surface - and finishing it the hard way (polishing it) is much, much slower and more expensive than cold-rolling.
I believe the Cybertruck manufacturing technology is fundamentally cold-rolled metal sheet based, with cutting/scoring and folding being the primary forming methods - plus some welding. (Even metallic screws are problematic: these types of stainless steel sheets take a lot of effort to drill through.)

This is so brilliant! Why not combine the two techs into an amalgamated foam-cast-stainless-steel sandwich?

In fact, come to think of it, aren't the landing legs of Falcon rockets made of foamed Al? ISTR that one of the first landing attempts was so hard that the foam compressed but held up the load. Just needed a new set.
