But battery research is ongoing from a century at this point, we can't possibly think that Tesla just came out of nowhere and thought a solution nobody considered before such as using less rare elements. It is most certainly a trade off and I'm not seeing where the cons are mentioned. Moreover, lithium-ion batteries have by far the most efficienty energy density, so what is tesla getting rid of, most certainly not li…

Every sentence of this is wrong. Disclaimer: I am no fanboy of Tesla; I think Tesla's lunch will be eaten by BYD, either alone or together with other Chinese EV manufacturers, in part because Tesla has been resting on its laurels for so long (still selling the model S!); but facts are facts. > But battery research is ongoing from a century... Tesla's claim is about motors, not batteries. Tesla has implemented solutio…

You realize that my post stems not from the original news but a discussion about batteries?

Ehh, Tesla just sold their 4 millionth vehicle (waited until then for investor day so they could flex), are breaking ground in Mexico shortly on their new factory, and are rapidly approaching $100B/year in revenue at a 25-30% margin (while other EV startups are teetering near death and legacies are slow to catch up). Constructive skepticism is fine, but strong evidence of their innovation capacity is available (espec…

I have been a huge skeptic of Tesla, but when you visit Europe the roads are FULL of Teslas, and in the US the roads are now full of them too. In Europe it's more bizarre because generally those consumers were sticking with European brands. Seeing Fords or Toyotas is very rare there, but Teslas are everywhere. That made me a believer. However, I do think the company is probably overvalued. I think Elon Musk does a lo…

Where in Europe, because outside Norway Tesla's don't dominate at all. [1] They had around 15% market share and the last few months that dropped.

Maybe because in Europe you have other auto makers that make electric and non electric versions of the same car so you just assume they aren't EV? The Hyundai Kona is basically the same outside except for the front grille and no exhaust. Unless you know that, you don't really know the difference. I would say (in Portugal) on my daily drives I identify around 6/7 Evs for every Tesla. And as I said, I probably missed some as I can't distinguish them

As far as I am aware, there is nothing rare about "rare earth metals". The only reason the west relies on places like China and Russia is because refining them is very very polluting, producing a lot of toxic by products. So we either do that locally and pay 100x more to fund the clean up after. Or we import from China and Russia where they apparently don't mind everyone getting poisoned. So this isn't really anythin…

The last time I went down this rabbit hole, I discovered one of the other reasons that China is effectively the refinement bottleneck is because of all the related patents that they've picked up over the years.

A world where you can't buy rare earth metals from China is also a world where those patents are ignored.

Any reason that Norway’s car brand popularity is a big deal in the larger scheme of things?

It has the highest EV penetration in the world. Nearly every single new car sold is an EV. It's therefore a great indicator about how various EVs will fare on a greater scale, perhaps.

Perhaps. The USA EV market outpaces Norway by a pretty large margin, and Tesla leads the US EV market in a similar way to Norway, I guess it depends on what data point is being looked for specifically. Relatively speaking Norway is a pretty tiny market to make large scale indications off of.

> revenue at a 25-30% margin I love how Tesla fans are so quick to applaud how much money Tesla is making from them. It seems most of "the mission" is (re-) building Musk's wealth. > such as their heat pumps The heat pumps that have been a problematic nightmare?

What problems with tesla heatpumps are you referring to? I haven't heard of any, works great in my car

Recalls and multiple software fixes.

Love Tesla or hate Tesla. Their engineering chops are unmatched. Be it hardware, software or manufacturing engineering.

You almost made me spill my coffee.

Tesla still CANNOT get their auto wipers to work correctly. This has been a feature on a Mazda 3 I had in 2007 and it worked flawlessly.

I assume that the relevance is that Tesla's claims don't count for much until they actually deliver. Elon Musk has a long history of misleading people about Tesla. Whether it's embellishment, overestimation of what they can accomplish, or outright lies is up for debate, but the fact remains that they habitually over-promise and under-deliver. I consider him and his companies to be completely untrustworthy. He could b…

Do you mean habitually under-deliver with things like making the crazy claim that they will grow at 50% CAGR? https://twitter.com/ICannot_Enough/status/161837414087616512...

Aluminum is really easy to fatigue and fracture. In a car that is vibrating and jostling all the time, this could happen surprisingly quickly.

Airplanes flying for decades are made of aluminum.

Their cables?

Musk has said that one of his companies will give paraplegics the ability to walk again. He's overstated and overhyped the autonomous driving capabilities a million times as well.

That is a goal and one of the end results if neuralink tech is successful one day, do you not think that idea is worth working on?
