The X factor in all of this is how defensible / non-reproducible a robotaxi is. If self driving ends up being easy to replicate or copy due to general advances in AI, no robotaxi business will sustain unusually high margins.

I mean this. It’s not complicated …investors view this piece of Tesla as a serious business. Tesla Has Built a Charging Business to Be Taken Seriously [URL unfurl=“false”]https://www.bloomberg.com/news/newsletters/2024-04-09/tesla-tsla-charging-network-has-become-a-serious-business[/URL]

Ah I see the oft quoted graph you are using. Well that specific study does appear to contradict what I said, but a meta study of multiple chemistries and studies does conclude that LFP is generally more stable. There are differences at various operating ranges that may result in different...

I voted against his comp package after this nonsense and know others who did as well. I wouldn't be surprised if he's turning tail based on the votes coming in.

LFP batteries are widely understood to experience less calendar aging than NCA batteries ... something around 40-50% of the degradation over time. You can google through various studies to confirm this.

In the short term yes, but they are/were widely viewed as a core revenue stream as EV's gain market share.

I'm highly highly against what the judge ruled. But I don't think Elon should be running the company any longer, yes. And a great deal of the run up in the stock was pandemic / ZIRP based. That's not to take away from Elon's role in the gains of the stock, but he's a liability now.

Completely disagree.

Yes, well, there's a very large number of folks here, including myself, for whom it is simple and easy to plug in every night. Having to plug in more is a non issue for most Tesla owners. 80% of Tesla owners charge at home, according to CNBC.

I don’t know what you mean by “putting up with low usable range”. If I only need to drive 50 miles, whether or not I have 100 miles or 300 miles of range in my battery makes no difference. I know roughly the range I need for the day, so I just keep the car charged above that. It’s that...

My Not a direct response but PG&E peak rates are going to be 0.67 per kWh for residential for four summer months. They're completely insane. Even off-peak right now I think we're paying 0.45 at least.

Nah, I've seen far too many cases when people just assume because a company has had success in the past they aren't about to f up. Guess what, they usually f'ed up. There's clearly enough info here to justify extreme skepticism.

I think 80 to 20 percent is the generally recommended approach. You might be able to go a bit lower in the pack for a bit more supercharging speed earlier in the charging curve.

It's far easier to believe Elon flipped his gourd. The Tesla Superchargers are widely and universally regarded as the gold standard for EV charging and responsible in large part for Tesla's pace of adoption so far. There's an external benchmark for success here that we all can see ... and it...

It’s not a fail depending on the goals. If you have the resources and the mandate, getting a bit ahead of the utilities appears to be a valid thing to do, although not the most efficient.

i don't know about that ... lots of superchargers are just not that full all the time. For me, superchargers are only for road trips. I imagine that's the case for a lot of people. Gas stations famously don't really make money off the gas ... they make it off the attached stores.

I'm not seeing a generous take on Elon's action here, to be frank. We don't know if there's something going on behind the scenes, of course, but if Elon is so out of his mind as to not understand that cutting the entire supercharger team needs additional context, then he's still acting crazy...

If it were a bad capacity estimate on a pack with healthy cells, why would the pack go immediately into shutdown? Wouldn't you expect the remaining estimate to drop unusually quickly first as it enters the tail end of the discharge curve, not just enter a shutdown state (especially when there...

Of course I do not know for a fact that this very particular mode of failure is what's going on in OP's battery, but it's called out in the presentation and clearly OP's battery is defective in some way. Averages and expected behaviors do not apply. You're assuming the battery pack is...

I believe the charging curve Tesla uses while supercharging mitigates a lot of the wear on the battery, correct? Of course supercharging isn't going to produce *less* wear on the battery than Level 2 charging, but the data out there seems to indicate supercharging batteries today isn't as scary...

There is a failure mode with li-ion batteries where the electrolyte oxidizes and coats the negative electrode. It causes relatively sudden / catastrophic loss of capacity. I would not be surprised if the BMS is just not well equipped to deal with this failure mode and tell you what is actually...

These look great. Would use one made for iPads. I found a pretty good holder eventually, but the vast majority seem optimized for loose insertion and not for holding onto the tablet in the event of an accident.

I agree the Jowua tray feels a bit bulky surface area wise, but I don't see any alternative to it ... it needs to sit in front of the steering wheels and it provides just the minimum amount of space to function as a reasonable desk. Any smaller and I don't think it would be quite as useful. I...

I ended up buying it. It's amazing if you need to sit in your car and wait for a bit. I got a ton of work done on it while the wife shopped ... and was quite comfortable the whole time doing remote desktop type work on my iPad. It stores away very well in the frunk. With a reasonably slim...

I haven’t had any comfort issues on day trips, but I did find my butt a bit sore after a 5 hour road trip. I tried a generic gel grid seat cushion off Amazon and it took care of the problem quite easily. Recommended.

You're right about the theory, but do you feel like 200 ft is a worrisome distance for WiFi over a directional antenna?

I believe you're missing the detail of "with a directional antenna or dish" that is being discussed. It does not sound like this has been tried yet? Regardless, if you are planning on getting rid of the car soon, perhaps this isn't a rabbit hole you want to go down. But wifi signals can go...

When it gets better, I could see myself buying it for kids or old parents to keep them (and others) safer. At the moment I'm the one that drives ... once a week and pretty safely, so it's hard to justify the extra expense above and beyond autopilot.

If you have line of sight, I’m not certain you need anything on the far end where the Tesla is.

A directional wifi antenna or dish should cover that distance pretty easily.

The big downside is it can only do 40F below ambient, which makes it more of a drinks fridge. To use as a normal fridge, you have to plan around ambient temps, inconsistent performance, lack of long term freezing temps (and certainly nowhere near 0F), etc. Compressor based fridges definitely...

Yes, this kind of stuff is scary. The frequency of these horror stories makes me believe the majority of electricians are just trained monkeys who have imitation learned and who don’t understand the theory behind anything they are doing.

Yes, is this about efficiency or isn’t it??? I believe lowering the car improves efficiency if OP hasn’t tried that yet.

I don't know, why wouldn't you? I've only driven it for one day so far, but in chill mode on the highway it seemed to be just autopilot with FSD lane changes that I can activate with a stalk. That was a plus for me. I did encounter some annoyances with the speed limit constantly going under...

I wouldn't pay 12K for it but i did find it pretty useful. The lane change stuff is annoying, but my sweet spot was putting it in chill mode and just using the turn stalk to make it lane change (which I figured out does work on the second day). I do have lots of thoughts but i overall was much...

Interesting situation overall and thanks for the additional details. It really seems like you're threading a needle here in terms of getting everything to line up, so it's still pretty difficult to zero in on an actual solution. But that carport situation sounds promising. One thing that does...

We liked the Phantom when we had it, but in hindsight, it really doesn't match up to the Tesla specific ACOPOWER fridge. The TesFridge, being specifically designed for the subtrunk space, properly vents the heat directly out of that space. The Phantom can't do that, so in addition to being...

Aaaand FSD was ready to go as soon as the install completed. I did get an email about FSD around the same time the install finished. Just in time for a big day trip in the morning!

Was stuck on 2024.2.7 this afternoon, got the update notification for 2024.3.6 around 7PM PT. Updating now.

OK yeah ... this is definitely not working. Blew a few hours on this. I can start the test but it never seems to ACTUALLY start. I never see the Test In Progress indicator on the HV system screen or hear the heater and fans running to burn energy. I suspect this is due to my charger being...

I rebooted the car and the test started right up. However, I'm not sure it's actually burning off energy like it's supposed to. Will give it some time...

Oh, there’s an internal gateway? Yes, it did ask me to unlock the gateway by holding the brake and right turn stalk before running the test. Maybe I should reboot the car and try again?

Feels like more detail on this situation is still warranted. How far are you from a plug of any kind? Is anything in the way? What exactly is your landlord against? Electrical receptacles are not particularly controversial ... maybe he/she doesn't want to put in a whole EV charger, but that...

So I prepped all week to run the battery health test before a big weekend trip, and I keep getting this message. The car is at 30% SoC, should be fine to run the test. It seems quite obviously to be some sort of connectivity issue with the server? But I have so many questions: 1. I DO have...

To be clear, I don't think going off percentage is really bad or anything. I think what most people end up doing is just fudging in a lot of safety margin to avoid doing too much math, so the rest of the discussion below is really just about those margins where one ends up needing to calculate...

Hi all, I'm looking for opinions on these laptop style trays ... aka: Jowua - Foldable Car Tray for Tesla In particular, general opinions of these products (do you love them, hate them?) and the ergonomics of how far back you need to put the seat to make it actually usable. I often find...

Those on-screen miles are rated miles of range, so I always mentally derate by some fudge factor + safety buffer. If i were trying to think about range in terms of percentage, I would still need to do that + convert to a battery percentage. Just seems like an extra unnecessary step. I do...

Yes, this has always confused me. How does using percentage help? Doesn't one end up having to convert that percentage to miles anyway?

I believe the ranges on the purchase page are EPA range numbers, which reflect a test cycle wherein the car is driven until dead. The miles on the screen have some miles taken out of the number as a buffer ... about 4.5%. So what you're seeing looks kosher to me. In a gas car without any...

Correct ... I went on a trip for a week. Went from 40% to 39%. Just make sure you aren't obsessively pinging the car or running features that keep the car awake and you'll be fine.
