What? NHTSA is going to strap Elon in for the oblique head-on collision test instead of crash test dummies.

This discussion is pointless as his behavior was what caused most of the other things that is hurting Tesla.

Its only now readily apparent to everyone because he made sure to make that public via his antics with Twitter. He's been this way the entire time, there's over a decade of evidence of it. I know a lot of it has been linked in this thread, where people that worked at Tesla and SpaceX said Musk was having to be babysat constantly because he was prone to being a moronic raging shithead that would ask such dumb questions that it would grind things to a halt as people tried to figure out how to explain things to him such that they could keep from causing a tantrum but also make it clear it wasn't something they would do because it was stupid. And so they did their best to obfuscate him from things and just pass along the buzzword shit for him to post on Twitter (anyone notice similarities about daily briefings with a certain former President?), where the format forced him to be brief enough to not interject much of his own shit to expose what a fraud, both simply too stupid to know what he's talking about, but also that he was in no way a genius or responsible for the success of those companies.

Twitter made Musk because the format forced brevity, which people mistook for intelligence. What really was happening is Musk was being forced to stick to "the facts" and post quite brief basic info that he was getting from the actual competent people at those companies. And his short quick answers to questions were likely because he was just passing the question on and then the simple answer back, not because Musk knew what he was talking about. Which makes it more understandable why he was so obsessed with Twitter and why last year happened. I think even Musk knew his status and success was built via Twitter, and that's why he wanted to control it. The problem is, he's such an incompetent egomaniacal dickhead, that he ended up just exposing what a bloviating full of shit dumbfuck he truly is.

Musk is Turmp. I bet if you go back and look at how Turmp was viewed at the same age as Musk, you'd find a lot of similarities. I've been telling people this for years. Musk got lucky in that he got surrounded by competent people that weren't crooks, which is why Turmp has so repeatedly been exposed as the buffoon he is. Musk is more intelligent than Trump, but they're on similar levels of ignorance when it comes to even their own businesses. That frankly is likely down to culture/family. Musk had parents that made sure he actually got educated. But functionally, they're both idiots who are too stupid to understand how much they don't know, but they have people fluffing them up for other reasons, and that in turn made them think they're just that amazing geniuses. But as they get older and more control, there's less people able to cover the reality. And Musk bought into the hype that he was the savior of mankind, when that wasn't even close to the case.

Similar thing happened with George Lucas, where when making the earlier stuff there were competent people that could cover, but once he was given cult leader control, it became obvious that he didn't know jack shit of what he was doing. And the people that covered for him had either left or were pushed out. This is what is now happening with Musk.

man, I'd really like to know Jim Keller's thoughts about his brief experience working at/with Tesla.

As for Lucas....Lucas actually does have some skills and talent--you can see it in his earlier stuff, like THX1138, American Graffiti which isn't all that great, but good enough for an early effort. He was actually smart with Star Wars when he stepped aside from the first shitty movie to let competent directors handle Empire and Jedi, and make his story ideas literate.

So, he definitely had some skills, he's pretty good at the "vision" thing but I think his main problem, which is probably similar to all these other clowns, is that he doesn't like people. Plenty of actors that have worked on his project have candidly mentioned that it's very difficult because he just doesn't know how to interact with people, give them instructions and translate what he wants to see them do. His late-life push towards complete technology and effects in film (when he earlier claimed that they were "mere tools") seems to be mostly his desire to remove people all together because I think they are just pests to him. ....but he's probably all fat and happy with his Disney billions now and not all that interested in ruining more things, so good for him.

Well Tesla stock wasn’t the only thing diving today. A Tesla took a 250 ft dive off road in California and fell to the rocks/beach below.


Was it Autopilot? Probably not. The driver apparently wanted to kill his wife and kids - at least that’s what they arrested him for. The car landed wheels down. He, his wife, and kids 9 & 4 had no life threatening injuries….





now...that's going to be an ad for Tesla and safety, lol.

I will say I'm impressed they walked away from that. Gas would've more than likely exploded.

Those batteries have a greater tendency to explode/start uncontrollable microfires that can go on for days...

Than gasoline? You got evidence to support that?

Not sure what you mean by micro fire, sounds like something I could get away from though.

I guess they are less likely than a gas fire, but it depends on what part of the vehicle is compromised?


The problem is that if you do start a fire, they burn much hotter and last much much longer. What I meant be "micro fires" because I didn't remember the term, is thermal runaway--where once you compromise a cell and can't control it, it can start compromising all the cells and is very difficult to put out. In some cases, these fires last for a couple of days and it's just best to wait it out.

I recall Elon the complete genius suggesting that Tesla start building the batteries into the chassis...which just seems like a terrible idea from a crash standpoint. Even if you don't compromise a cell to start a fire, this makes it incredibly dangerous for the passengers and first responders, because you might electrocute yourself touching the door. This is already a problem for F1 and F-E cars where the protocol is often to keep away from the car after certain types of crashes if the MGU-K or whatever is compromised and now the entire chassis is hot. Drivers have a few safe spots that they can touch when climbing out of the car, but that's about it IIRC.

I'm not sure how Tesla batteries fail, but there is a reason that aircraft lithium batteries are inside a fire/explosion proof box.
There is a reason aircraft fuel has nitrogen ventilation on it too. While still having tons of other anti-ignition regulations.

I'm not debating that Li-Ion can burn and be very bad when it does, but I don't believe car battery fired are more common than flammable fluid car fires.

Yeah, I agree a Li-Ion fire is likely worse than a gas fire, but I think it's less likely. There is the issue with location of fire too.

There’s a lot of engineering controls to prevent thermal runaway of a battery cell and pack. The basics are to keep a failed cell from igniting its neighbors. You do this by limiting the size of the cells, keeping each cell in its own housing with pressure relief so a failed cell can vent without exploding. There’s also a bunch of electrical controls to prevent overcharging or depleting the batteries too low.

That is not true.

Gas vehicles spontaneously ignite all the time. But they rarely have "micro" fires, they are nearly always quite major.

Gas vehicles also have a much higher chance to spontaneously ignite in a collision. The pressurized fuel system will spray aerosolized fuel if damaged, extends the length of the car, and also pressurizes the gas tank. This tend to trigger massive, hot, sticky, and fast fires.


It is much more difficult to get Lithium burning, and when damaged it typically takes longer to start lithum burning. But once it is burning it is going to burn for a long time.

Not to mention engine oil, ATF, and power steering fluid will all burn too. Power steering is mostly electric nowadays, but a normal gas car has a lot of oil and ATF onboard.

All you need is an internal short from the impact. Batteries have amazing initial current to a short, so it's can literally be an explosion. You must have seen some of those spectacular Tesla car fire videos.

The cells are all fused off from each other. Like an automobile fuse, but connected to each individual cell.

It is not enough to have a short in the pack.

In order for a fire to start, a short must occur inside an individual cell. Even if one cell catastrophically explodes, that is not enough to start a fire. Each cell is surrounded by coolant, and the energy from one cell going pop is not going to breach the cell next to it instantly.

Cells need to be compromised and boil off the coolant that surrounds them to start a chain reaction. This is not something that just happens. It takes time. It takes either massive damage or a manufacturing defect.


But yea, once a chain reaction starts, it is not going to stop.

Almost all the fire risk goes away if Tesla switches fully to lithium iron phosphate batteries (no thermal runaway, non-toxic, heck you can usually drill holes right through them without issue).
plus LiFePO4 batteries tend to last 5x to 10x more cycles. Aren't they used in the Chinese Tesla vehicles?

I know they are used in Chinese Tesla Standard Range + Model 3s. For the long range and performance Model 3s they are still using the normal chemistry.
