One thing that I have been wondering: Do you know if it is 130% of base pay or 130% total compensation? My understanding is that every Tesla employee is granted some stock options, which is different to many other companies who only grant options to management and those working in...

In all seriousness, this is exactly why Tesla was smart to make one giant OMG-the-sky-is-falling price cut (even if it scares the bejezus out of wall street and gives FUDsters ammo) instead of a series of smaller price cuts. Tesla is training customers that this is their one chance to get a...

Not quite, but they’re getting close. $19B in assets and $3.6B in liabilities as of Q3, so ~15.3B in stockholder equity. Divided by 921M shares is just under $17/share. Since we’re nearing the end of Q4, and Rivian is lighting about $1.5B (inferred, because they only state cashflows on a 9...

I would actually disagree with that somewhat. Throughout the 90's, and most of the 2000's, companies increasingly outsourced manufacturing to countries with a low cost of labor (and more "flexible" environmental regulation). Consequently, the cost of manufacturing in real dollar terms fell...

Exactly. The other issue that's starting to come into focus is their unit production cost, which is currently looking to create negative gross margins: Best case: Assume Rivian can produce 25k trucks this year with zero growth of Cost of Revenues. That means they need to produce around...

Activated carbon (charcoal) for poisoning?

I actually don't need to do anything. I don't appreciate the accusatory tone, so I'm going to log out for now. See ya.

Because I ctrl-f'd for "sbc" not "stock-based", so I didn't see it the first time. Tesla doesn't break out SBC into the various Opex buckets, so it will make the table a bit of a mess if I go back and edit it now. I'm getting tired of this. It's clear that Rivian's opex is highly...

Because doggydogworld claimed they were OTEs. Rivian doesn't claim they are (that I can see), but keep in mind that SBC is a non-cash expense in all cases. Happy to edit my post to add that if you can provide the number. I didn't easily find it in the deck.

Personally, I would need to see: Positive GM (both companies currently have COGS > 8x revenue). If you're taking a loss on each unit, volume doesn't help you. "Reasonable" (whatever that means) production expansion. They either need to start hitting their targets, or fail to hit really...

From page 15 of the FY2021Q4 Rivian shareholder letter, we have (in Millions): Total One-time-ish (SBC & donations) Difference R&D 726 277 SG&A 682 277 Other 633 663 Total Opex 2071 1217 854 From page 30 of the Tesla shareholder letter, we have (again, in millions): Total...

Not really practical, unfortunately. The problem is that any published “n day & x miles” safe harbor policy will inevitably lead to people who intend to resell cars to hold cars for n+1 days after driving exactly x+1 miles. So it doesn’t stop unscrupulous dealers. Tesla does need to ensure that...

I wonder if you could share (or point me to a post where you already did), at least generally, how such a model is built? Are you assuming some supply and demand curves and asking "what if I shift the curve like this?" I think many of us could benefit from learning how to build models like...

Better yet, ask them to calculate how much time they spend at the gas station each year for their weekly gasup. Then compare that number to the hour spent supercharging once or twice a year. If time is money, how can you not buy an electric car?

I know that. The point is that if/when congress decides to levy a "direct" tax, they will need to ensure that the money derived from it is spent in the various states in proportion to their populations. Actually doing that has been so difficult that no congress has seriously tried. Again, I...

It was previously speculated that BBB EV credit would be paid for with a wealth tax, which falls under the category of "direct" taxes. The constitution requires that revenue raised by direct taxes be spent in (or given to, depending on your reading) the various states proportionally to their...

One of the challenges with batteries, however, is their weight. Unlike ground vehicles, weight has a significant impact on performance (takeoff runway length, climb, and energy usage in cruise). Last time I looked at the specifications from a few electric airplane startups, and the...

First, I shared my model because I thought the results were interesting. Your response comes across as weirdly hostile and antagonistic. I provided the code I used for the simulation. You're more than welcome to modify it with more realistic charging curve. In fact, that's why I provided...

Building an overly simplified model in R (since I happened to have the REPL open... and I'm a dumb physicist who prefers not to do math), I get the following time-averaged charge power per car (all starting at 5% SoC): Final SoC Charge Time (Hrs) Avg Power (kW) Percent of Peak 0.5 0.15 214...

That's closer to what I see on Levels: Levels.fyi | Salaries & Tools to Level Up Your Career

This is such a bizarre argument. First, there is no way for your car to know for certain the exact number of miles remaining. You, the driver, might suddenly decide to take a left turn up a hill. The car has no way to predict that. Suddenly your kWh/mile skyrocket. Your remaining miles will...

Porsche advocates will argue till they're blue in the face that Porsche never technically promised 350 kW for the Taycan--it was only the Mission-e concept car that was promised to have 350 kW charging. 🙄 You probably remember the 350 kW number because Porsche made a big deal about it in press...

That depends on the trip, of course. I'd love to see a Taycan can do Fremont -> Hawthorne nonstop, like this. 360 miles should be easy for a Taycan 4S driving the speed limit in range mode, right? Gas cars typically have at least a gallon (roughly 25-30 miles) with the needle on empty...

For what it's worth, I've been lurking on the Taycan forums. The consensus among owners there seems to be a few things: Porsche used a pre-production BMS with larger top and bottom buffers when doing the EPA testing. Owners report a larger usable capacity than is indicated on the EPA filings...

You said they didn't make profits from the cars until the Model 3. Well, that is not really true. Tesla had positive operating cashflow from around 2013/2014, before even the X was launched (you can read the old 10-K filings for yourself on the SEC's website or Tesla's investor relations...

Let's say you drive 75 miles, and you get 250 miles Real World Range (RWR) at 100% SoC. You charge 45 miles overnight. Monday morning: 250 miles RWR Monday evening: 175 miles RWR Tuesday morning: 220 miles RWR Tuesday evening: 145 miles RWR Wednesday morning: 190 miles RWR Wednesday evening...

This might be a slightly unpopular opinion, but I think there could be another reason for this. Consider that Citadel is both a market maker (i.e., they can sell naked shorts) and an interested party in Melvin (the biggest GME short). We have also seen some obvious attempt to drive down the...

I don't know how Tesla's comp structure works, but that would be highly unusual for a public Bay Area tech company these days. Most offer RSUs rather than options (I don't know anyone with options who isn't working for a startup), and the RSUs usually vest in blocks every 6 months. This also...

I wonder why not? Is the communication protocol different? The people selling the adapters seem to think it is possible to charge a Type 1 car on Type 2, or vice versa.

According to this thread, that's the reservations phone number. They have nothing to do with post-sales customer service. Makes it hard to believe your questions are being asked in good faith.

I wonder if a Type 2 to Type 1 adapter would allow the Tesla CCS adapter to charge NA cars? European to US CCS Combo 2 to CCS Combo 1 EV Quick Charger Adapter – EVSE Adapters

Hmmm... I'm not sure the Model S actually has that much more usable battery. Over on taycanforum.com, some owners are noticing that: When extrapolating the total battery capacity from the car's reported kwh per mile, the capacity of the Taycan pack is significantly larger than what Porsche...

I was more responding to your stated understanding that exercise is determined by the price (closing or otherwise). Options are typically not exercised when they are OTM (whether that is during or outside of normal trading hours). But they can be. My point is simply that you can't assume that...

Option exercise is entirely at the discretion of the entity who bought the option. OTM options are typically not exercised, but they absolutely can be exercised. As the writer (seller) of OTM an option contract, you are typically not, but absolutely can be assigned. You can verify this for...

I probably don't understand the mechanics of the market as well as some others here, but I think this is still not quite right. My understanding is that the rule requires that any short sale orders must be added to the order book at a price which is higher than the current best national bid...

Your comment got me thinking: Is it possible to drive any car at 120 mph for 2 hours on the autobahn? Other people have had the same idea, and it looks like the answer is a firm no[1]. The longest unlimited stretch of autobahn is less than 200 miles. [1] What is the longest stretch of the...

Wk057 has been writing about his exploration of Model S systems over in the "Let the hacking begin..." thread in the Model S forum. For what it's worth, 77 kWh matches nicely with the capacity he calculated by discharging a sample of cells.

So, Tesla has a major advantage that I think you're overlooking: Real-world data on charging (and discharging) EV batteries at Superchargers. Every Supercharger is (probably--I'm speculating here--but I'd be just floored if they weren't doing it) connected to Tesla HQ for things like...

So I think you're thinking of the related (but different) concept of thermal efficiency as it relates to heat engines, primarily because practical heat pumps (i.e., air conditioners) usually have COP well over 100% [1]. Thermal efficiency, of course, can never exceed 100%. COP measures the...

An efficient transcontinental route is better than an inefficient one, yes. But any route is better than none. It forces BEV skeptics to make a much weaker argument: Before superchargers, they could say something like "It takes a BEV a month to drive from Chicago to Seattle. [Or Chicago to...

If you mean the minimum acceptable speed for road trips, then we are in complete agreement. But I've seen people refer to the Model S in particular (not just BEVs in general) as a leash. Why? Because they don't know that Supercharging exists. You have drag them by the ears, kicking and...

What you're saying is all true, but the Superchargers are and always have been partially about marketing. If you go hang out on ICE forums, you'll see people talking about how BEVs are a "leash" that ties you to your home. We all know that's not true, yet it's a common belief among the...

Aury, I really think you don't fully appreciate the safety hazards associated with high pressure gases in general and hydrogen in particular. First of all, when compressed gas containers fail, they usually fail catastrophically. Failure of a cylinder of even an inert gas (say, any noble...

Its even true (though to a lesser extent) in many places in the US. Consider the southwest: Once you venture outside the suburban outskirts of big cities like Los Angeles and Las Vegas, it's not too hard to find a stretch of desert interstate with 20 to 50 mile gaps between gas stations--and the...

I guess it depends on how the generator was brought... just a thought here, but most tow trucks already have a PTO to run the hydraulic pump, and PTO generators are an off-the-shelf item. Based on some back-of-the-napkin math, it seems like a purpose built generator (maybe with a hydraulic...

Doubling the battery capacity only raises the curb weight by only about 20%: (3300+660)/(3300) = 1.2. That's less than four FAA-sized adults. In a pure hill climb or on a race track, sure, you'll only get about 66% (2/1.2=1.66) more range instead of 100%. But you'll get within 1% of 2x range...

Why not Option C? Option C: Get a i3 with a 35 kWh battery instead of a 22 kWh battery. At about $300 per kWh (which is what it costs Tesla, if you believe they earn a little profit on the $8k 60->85kWh upgrade) you could just about do it for the same price as the gas REx upgrade. There'd...
