DISAGREEAnd I say that while I consider train driving to be one of the most soul crushing jobs, a role that should be automated away. But the economic arguments in favor of automating train driving are not overwhelming.
Oh-kay. So they aren't willing to say *which* materials they think there's a shortage of. Nickel's easy to get, there's lots of nickel. Lithium? Cobalt? Graphite?
an occasional phantom breaking that comes out of nowhere.
It only stands to reason that trains pulling 120 cars of goods are a lot more efficient than trucks weighing 35,000 kg or so including the weight of the truck. When I'm traveling, what I see are miles of railroad tracks that are seldom occupied and roads clogged with trucks. This seems to me to be a very inefficient way of delivering goods. Yes, trucks are needed at the end points, but a lot of shipping could be done by trains. This would not only reduce road congestion, but it would reduce road maintenance by a large amount.
Plausible. I'm not sure you're entirely right, though.
It's not the actual raw material deposits that are in potential shortage, but the extremely high grade Nickel, Lithium and Cobalt needed for high quality batteries are highly processed through high capex plants which normally take 3-5 years to ramp to capacity.
That is Gumperson's Law, a corollary to Murphy's Law of Experimentation. "The desirability of an event is inversely proportional to its probability." To wit, if you drop a piece of toast it is likely to land butter-side down.
Works except that you'll never get the bread and butter to stay on the cat for more than 0.03 seconds.
Anyone using navigate on autopilot knows highway driving is already now at L3. It still has the annoying nags but we are doing L3 on highways. There is a large gap in perception vs reality of where Tesla is with autonomous driving technology.
False positives.Generally very smooth. Anyone in my car would not know that I am not driving except for an occasional phantom breaking that comes out of nowhere.
Spot prices of battery-grade nickel sulfate, lithium carbonate, etc are all down - some significantly. This cannot be the constraint. They can buy at low rates on the open market.
Which week/month? Volatility likely won't be going away.What would you think the stock price will be at, if this turns out to be true a year from today?
DISAGREE
You have clearly never been beholden to a highly unionised and greedy workforce of train drivers. Total comp for a London tube driver has now surpassed £100k per year. They have achieved this by organising regular strikes every year that shut the city down for 2-3 days at a time, causing untold economic damage. This may not be the same thing as financial cost to the train operator.
I don't think these is a significant quantity to purchase at short notice on the open market for true battery grade of any of these materials, the vast majority are sold on long term contracts. Sumitomo/Panasonic could perhaps buy a small amount of battery grade materials on the open market, but it would not be to Tesla's exact specification and I don't think it would be easy to simply substitute. Battery grade is a misleading term, it is an umbrella term for many different products and they can't all simply be used interchangeably across different cathodes.
That said, I think it unlikely that lithium hydroxide was the Q1 bottleneck.
Note that each of the individual chips are NOT 100 tops. Both chips (the board) is what provides up to 10x increase that Elon has previously mentioned. HW3 is an actual board. This 10x is over half of 2016 Nvidia's Drive PX 2 which is about 10 tops.I.e. the true comparison even based on your 10 billion neurons full visual cortex estimate would be a computing capacity of about 100 TFLOPs - close to the computing capacity of a single Tesla chip. (and there's two of them)
Do you currently have to pay attention and monitor the environment and the system's performance?
If Yes its still SAE level 2, if No, then its SAE level 3.
Level 3 allows you to watch a movie, read a book, etc because you no longer have to pay attention.
Level 3: Environment detection
Able to detect the environment around them, level 3 vehicles contain the lowest-tier system that is classified as an automated driving system as opposed to a manual system. With this more advanced technology, level 3 vehicles can make informed decisions for themselves such as overtaking slower moving vehicles. However, unlike the higher rated autonomous vehicles, human override is required when the machine is unable to execute the task at hand or the system fails.
Level 3
An Automated Driving System (ADS) on the vehicle can itself perform all aspects of the driving task under some circumstances. In those circumstances, the human driver must be ready to take back control at any time when the ADS requests the human driver to do so. In all other circumstances, the human driver performs the driving task.
