I’ve found the charging to be a non issue. It’s basically timed with bathroom / food breaks.

I have found charging to be a huge issue, and so has the majority of Americans (clearly). But why let facts interrupt an HN circle jerk?

How many hundreds of miles do you typically drive at a time?

Maybe "cultists" is a better word than fans, with Musk as their guru.

The model Y is a genuinely good car... I can't think of an automaker with better software. I've recently been shopping for another electric SUV and to be told that to get charging stops on your long trip 'through an app on your phone' instead of built into the navigation is.... Wild Edit: it needs to be said that I consider a car a solution to the A to B problem, and nothing more :) This was one of the premium German…

> I can't think of an automaker with better software.

So I have a Zoe, tesla has much fancier software, the remote control on the phone for the tesla is great.

the Zoe has a chugging navigation system and no adaptive cruise control.

But it has buttons. Its cheap to run and is super easy to drive. Its also faster than most ICE cars.

More importantly its smaller than a model Y, and I don't look like a massive penis driving it.

Also the doors shut properly, the trim isnt hollow and its not falling apart.

The software is shite though.

So the only two options you can imagine entail his detractors being irrational and emotional? You can not comprehend that anyone can have any valid complaint regarding him and his behavior at all?

Musk has accomplished some remarkable things, by having grand visions, ruthlessly executing on them, and being willing to repeatedly take on a massive amount of risk. If that had been all, I don’t think many people would be decrying him like this. It’s still easy to justify admiring those bits, if you’re so inclined

But he has also done a lot of things that make him unlikable and are harder to justify. He happily whips up massive amounts of hype, regardless of how likely his claims are to actually manifest (which is a large part of why the Tesla stock price is where it’s at). He sucks himself off at every possible turn, and takes dubious personal credit for a lot of things his companies achieve. He is vindictive and has exacted retribution on people with much less power than him (or pouts about it in an undignified fashion when the opponent is too powerful to crush, like the SEC). He has an easily bruised ego and lashes out in a very childish manner (remember the diver he called a pedo on Twitter). He enters into realms he has no expertise in and proclaims to the whole world that he has all the answers. He directly interferes in US and world politics by wielding his wealth and influence, sometimes with disastrous results (it doesn’t help that his political views usually are unsophisticated and immature, especially since he acts so certain of them). Etc, etc

Basically, he’s a dickhead that thinks he’s the best in the world at everything, and many of whose actions are detrimental to both individuals and the world at large. He doesn’t get a free pass for that just because he’s done some impressive things with his businesses

Yep. Prismatic cells have poorer packaging-to-material ratio (circles are optimal). They offer better thermal properties, but thermals are not the main limiting factor anymore. And the US automakers tried prismatic cells before. Chevy Volt used them in 2012!

How are circles optimal??? Circle packing = 90% Blade battery packing = 100%

it's not just a basic geometry problem, it's an engineering problem. You need to account for far more details.

Letter grade E?

https://en.wikipedia.org/wiki/Academic_grading_in_Sweden Not quite failure in Sweden. Something about how the car is not quite bad enough to break the lease. Thus explaining the joke in such excruciating detail as to kill any humor.

Haha makes sense now thank you.

There is no “subject to interpretation”. The costs they charge for launches are lower than any other provider by a significant margin. And fundraising docs have shown many times that the Falcon launches make money and Starlink was just starting to make money about 1.5 years ago. > What we clearly know is that using software development methodologies to building critical hardware is as a bad idea as it sounds. This me…

Yeah, Falcon rockets are a regular workhorse kinda rockets. Nothing special about them. NASA could have made their own but someone decided it needs to be outsourced. I mean they did a fine job there, but nothing to write home about IMHO. And on the topic of reusability I can't really find much info besides that it is just partially reusable. Not sure what the point of it actually is. I guess what matters is the launc…

> I guess what matters is the launch price?

It’s a commercial launch company. Of course the price matters and it being so much cheaper than the trash from ULA, Russia, etc is why there has been an explosion in new space endeavors (see the bandwagon launches).

> Nothing special about them. NASA could have made their own but someone decided it needs to be outsourced.

“Anyone could have done it bro,” is such an ignorant response. Nobody did it and there was the entire launch industry to collect if they did.

Even if NASA could have, they were derelict of duty in enabling space utilization because they never did it.

> And I heard they got billions in subsidies but have nothing to show for it.

Should probably check stuff before you repeat it. SpaceX has not received billions in subsidies for going to the moon. It did win a contract to do it, which as the name implies has required deliverables.

Since this is a discussion about electric vehicles, I thought it could go without saying that I was talking about batteries in such vehicles, not batteries in consumer electronics that are 1,000 times smaller. To use an analogy: If someone stores a gallon of gasoline in a single-walled plastic container, that's probably OK. But storing 1,000 gallons of gasoline without certain safety measures is unsafe. So it goes wi…

Apart from Tesla very few EVs ever used cylindrical cells.

BMW is moving the other way, from prismatic cells to cylindrical

What evidence is there for the 'dump' part? Mr Musk is a strange fellow indeed, but he's not guilty of all the vices and sins. Just plenty enough of them.

That’s a fair point, but a combination of “fake it ‘til you make it” together with extracting massive “compensation” before you actually make it amounts to pretty much the same thing.
