I thought this mini-documentary on Tesla's current issues was pretty interesting, its pretty balanced if anything.

^I really find the bit on the subsidies quite interesting.

Most companies get berated for losing a lot of executives in a short period of time, as a sign of doom.
But Tesla has taken it to the next level as they are losing 4 members of its board in one announcement that came out today
Tesla Shaking Up Board With Long-Time Insider Steve Jurvetson, 3 Others To Leave

A new study from Germany reconfirms what a lot of us already know, a battery pack in a Tesla is so big that its manufacture is about 10 years worth of co2 emissions pre-emitted before you start driving.
Electric vehicles in Germany account for more CO2 emissions than diesel ones, according to a study by German scientists.

The CO2 numbers are all wrong it's just a fake study as we have seen 100s of times.

And if you find the tiny bit of subsidies Tesla has gotten how about the $5 Trillion a year the top 50 oil companies get in subsidies.

Cue Hillhater or Beastie saying how it's all because Audi isn't focusing on coal-fired cars.

I just went ahead and muted both of them. Had enough of that nonsense :)

From the article:

============
The Audi e-tron, once dubbed by avid Tesla critics as a potential “Tesla Killer,” is reportedly running into production problems due to a constrained supply of batteries and a slower-than-expected delivery of electric motors. These production problems have reportedly caused Audi to postpone the release of its upcoming all-electric car, the e-tron Sportback, to 2020, roughly a year later than its intended 2019 release date.
============

Looks like Audi may have to send some people to Palo Alto and Sparks to see how it's done.

Yep.

I got a laugh on another forum about how EV's were killing everyone because of all the radioactive waste that comes out of their battery manufacture. Then it was toxic chemicals. Then it was child labor. Now it's CO2. Tomorrow we will find out that EV batteries cause illegal immigration, terrorism and bad breath.

If your first smear doesn't work, just keep tryin em until you find one that does!

Pretty sure chemtrails come from somewhere in Sparks, NV :mrgreen:

OT since it was a Model S, but the video is pretty scary :shock:

They're suspicious that it was some kind of staged event.
Looks like a classic YouTube lipo pack-stabbing fire video, except car-sized and with no one there to stab it.
The thing that really makes this video special is the fact the cameras were recording BEFORE the fire started, there have been a fair amount of "Parked Teslas" bursting into flames, just none recording the incident from the very start.

Very same Tesla model being the "Model S" fire happened Today, the guy was just driving and noticed something was wrong and pulled over where the car went up in flames. He called the fire brigade immediately but still burned significantly.

The belief from people who are betting against Tesla is that there are so many Model-S and Model-X mystery fires that their only real question is why doesn't it happen to the Model-3. Apparently, the model-3's have NOT suffered from spontaneous combustion problems like their older counterparts. So in this area, the Model-3 is a winner.

Today was Tesla's "Autonomy Day", where they go over their latest work in self-driving technology.
CNBC which is normally ridiculed for pushing Elon/Tesla's hype was far more in the middle this time around, maybe years of seeing presentations designed to appeal to sharemarket investors makes it easy for them to see it for what it is.

My biggest reason why I haven't believed in non-LIDAR self-driving solutions is the amount of computing-processing power it takes for a mostly optical camera (non-LIDAR) only based driving system to really understand the world around it.
Tesla has put together a custom processor to try and achieve the goals of mostly just optical camera based driving, and their presentation video is far more convincing than their previous stuff.
But Tesla came out and said they have been putting their new processor design in all new Tesla's for roughly the last month now and are still claiming they are more or less 1 year away (which really means 2-3 years away) from FSD.

To me one of the bigger giveaways was when this lady reporter asked about the next released FSD computer and what will it be able to do that the new current one can't do, and the head engineer neural-net processor guy said the most hilariously honest thing to help Elon answer the question, that is he tries to whisper to him "safety"

^Full Youtube Tesla "Autonomy Day" video here.
So what this really means is that while their new FSD computer might be a remarkable leap over what they have had before, to really get true safety FSD level driving it won't happen until they have their next generation even more powerful FSD computer is completed, IMO.
I really think Elon had hoped to come out with even more hardcore promises of timelines rather than just "next year" but while their new FSD hardware is a big improvement he couldn't say "its here" which I believe he really wanted to be able to do so because of the falling "deliveries" numbers. The stock is obviously going to about to get hammered in my opinion.

It seems like its taken Tesla years to finally work out exactly what they really need for really reliable non-LIDAR optical camera based driving and they are inching towards that goal, but aren't there yet.
I think if other companies want to copy the optical-based zero-LIDAR FSD approach it won't take them that much work to catch up but definitely "appears" Tesla has a lead. I actually do now agree that LIDAR is just too expensive and messy long term, I am convinced a cheap LIDAR technology will never come, and that is its biggest problem.
what self-driving cars really do need is a lot of camera optic inputs and an incredibly powerful computer working out what's going on, so far some of the Tesla crashes on autopilot have been so dumb its just scary, https://www.youtube.com/watch?time_continue=135&v=nWaz2jer8Ek
so they still have a lot of work to do.

While folks might like what Elon is doing, it's important to remember just how much "it's about the money" all this can be argued about.

Consumer Reports: Tesla Must Prove Safety Before Claiming “Self-Driving” Ability
https://advocacy.consumerreports.org/press_release/consumer-reports-tesla-must-prove-safety-before-claiming-self-driving-ability/
“But instead of treating the public like guinea pigs, Tesla must clearly demonstrate a driving automation system that is substantially safer than what is available today, based on rigorous evidence that is transparently shared with regulators and consumers, and validated by independent third-parties.

Tesla has a restringing order against at least 1 short who was stalking employees as well a group of shorts have planned to make Teslas catch fire in order to profit from the stock dip. Why do you think the camera was rolling before it started catching fire??

Actually that looks like a "screener" of a surveillance video that may have continuous recording.

Yeah I didn't click his link I thought it might be another video.
That one does look suspicious for sure. Its odd how fast it became a big fireball.

Chain reaction perhaps ?

Doubt it. Usually 1 cell ignites then another but the modules in a Model S are separate to make a smaller fire. So its more likely you will see some smoke then a small fire then a big fire if all the modules ignite.

Isnt that a description of a chain reaction ?

Sure but that's not what the video shows.
 
To get a fireball that big, a large section of the pack would need to short. The individual cell fuse wires are supposed to prevent more than one (or a few) cells from blowing in this case. Perhaps the individual cell fuse wires don't perform as advertised.
It does not appear the car is being charged at the time, but hard to say for sure.

In an 18650 battery pack without protection (eutetic material between cells, very powerful active cooling) then one cell lighting off will get the cell next to it to ignition temperature. This has been demonstrated quite a bit.

The individual fuses will protect the pack if one cell sees a dead short, but not if ignition occurs.
 
If the video is real, then it was way more than just a few cells going off. Normally you see a pack burn much more slowly where one or two cells at a time are venting and it propagates from cell to cell. If a whole bank or section of the pack somehow shorted, then you could get a lot of cells heating up at the same time and have something like the video.

Perhaps. A lot depends on how the pack is built. If it relies on solid heatsinking to move heat from one cell to another to a heat pipe, then adjacent cells may reach ignition temperature a lot more rapidly. If it relies on aircooling, it may take far longer for the heat to propagate through the air.
