Optimal is set charge limit between 50% and 55%. I choose a random number between 50 and 55% each time I reset charging (to help BMS recalibrate). Not much difference between 70% vs 80%, but there is a step in degradation around 55%, below that is better. The longer interval of time the...

Elon is unfortunately that very juvenile person who is into that

I've said it before, whenever Tesla does something weird or uncomfortable or annoying, It's Always About The Money. The good exception was going to lithium-ion 16V battery to replace lead-acid, but even then there was probably enough warranty service cost to justify. Wipers suck because Elon...

and similarly with inference compute burden for that equivalent we'd need much higher rate bitstream, much more training, and a huge net with screaming fast giant hot compute on giant 4 nm chipsets.

That's definitely the case, they really don't want to deal with tires and alignment which others can do better and cheaper. To answer your other question: for most uses the Hankook iON evo AS seems to be the best non-performance replacement tire now. Superb efficiency, quieter and 50k warranty.

The tread blocks with grooves and holes are there for rain and snow only. Like a race car, grip for completely dry conditions is best with a smooth flat tire surface. They're called "slicks" sort of ironically because it's actually the opposite---most static friction. Unless you hit water in...

Complex yet but not remotely several orders of magnitude more power hungry and large. There are many such startups and mainstream electronics companies https://arberobotics.com/product/ https://www.nxp.com/company/blog/the-importance-of-imaging-radar:BL-THE-IMPORTANCE-OF-IMAGING-RADAR...

Right now no Tesla being sold has anything close to autonomy, it's all L2+ driver assist and for the product that Tesla is currently selling, a cruise control radar could help. Elon's complaint about sensor mismatches is tendentious bullshit--you work and do best statistical sensor fusion you...

Well then that's one reason why other autonomous driving companies use direct sensors to reduce perception errors, and devote more machine learning and computation to policy.

I guess I don't understand the problem---I plug in when I get home but the charging is automatically at night and complete by 6am (end of my low cost electricity period). If you have a time of use electricity plan (which can be beneficial with EVs), later charging is better as well.

I'm not---humans are better in the fovea than the 1280x960 of HW3. It can guess at a car at distance, but not be sure, and definitely not be sure about its velocity. That is a harder job than image classification, as you need to estimate relative size changes with high precision and if its 4...

all expected by the technology. The HW3 cameras don't have that much resolution and can't easily distinguish dots far away as cars, much less accurately size them and estimate relative velocity. That takes multiple frames and filtering and the object needs to be big enough on the pixels that...

What I meant is that the value of each sensor in determining truth varies depending on condition and one could make a machine learning model (given enough ground truth data in multiple conditions) to give the best estimate, weighting each sensor accordingly. There are many startups in that...

The Model Y P tire is Michelin Pilot Sport 4 AS, which is already a very good handling tire for an all season, if not the best. It's definitely not the most efficient though vs EV focused efficiency tires.

The MXM4s are not exactly the same as Energy Savers but likely the equivalent for a larger, heavier car. They have been the standard tire for the 18" wheels on Tesla 3 model. The tire company will share tweaks, production and engineering across product lines. Historically there was a strong...

Hmm for 245/45R19 for 2023 Tesla S I see Hankook EVO AS on Discount Tire.

The right thing these days is to build a machine learning based sensor fusion model which can also model the likelihood of which is more reliable in which situation and balance accordingly. Like at night with strong glare, the radar is probably pretty good, but in bright daytime on crowded...

Hankook ION EVO AS is getting great reviews on ride comfort and noise, and they they have top efficiency too. I think for what you want the Pirelli Elect would be better than the comparators you mention.

NMC does have fast degradation at 100% more than 90% right? And most cars outside Tesla are NMC, not NCA.

the people who supercharged often probably didn't have home charging, and they likely drove their cars down to lower SOC on average than people who set their car to 90% and stayed between 75-90% almost every day, which is not great for calendar aging. So as we've been saying, cyclic aging...

Hankook ION are not the same as Kinergy. Kinergy is an old design, not well rated by anyone. the iON evo is an entirely new model and production process.

I've said it here before: anytime Tesla does something weird and uncomfortable and annoying, it's Always About The Money. I really wish now JB Straubel would take over as CEO

One more update on my personal car: the above measurement might have been pessimistic because of BMS calibration error. A full charge recently gave 344 miles at 16 months. I am now setting charge limit to a random number between 50 and 55% each night, that seems to get more BMS recalibration...

The HW4 camera is starting to get good enough, but it's not clear if there is enough processing power to use it with current hardware. And most people still have HW3. This is not an original thought of mine but one I read: Waymo using lidar since 2007 (they are out of the DARPA challenge...

I personally think high-res radar is the best additional sensor technology: eventually cheaper than lidar as it's all silicon, higher power efficiency, no mechanical/optical pieces which are fragile (AESA scanning like on military), more resistant to poor weather than lidar or vision, and it can...

That's the difference between a cool demo (acquire lots of data automatically and train) and a product. All those events would have to be annotated manually as to what is happening, and also semi-automatically as to the location (state or region perhaps with similar rules) and encoded in the...

And eyes are on double gimbals (eyeball and neck), substantially higher resolution in the fovea than the cameras, and stereoscopic. And the real problem is now in planning more than perception. Elon is a great example of CEO speak --- drop what they think are clever nuggets (but which are 14...

I'm not sure 11.4.7.2 is better than 11.4.4 and may be worse

Agree. I think the main issue is people buying the P with summer performance tires and low treads and then saying it eats tires because of the weight.

I think the main difference is the types of people buying those cars. People buying a 500+ HP ICE car will be a small group of enthusiasts who understand tire-tradeoffs and have accepted the need for increased maintenance/wear costs vs a conventional vehicle. But there are many M3LR and...

True, may be production capacity issues. The iONs are made in Korea and part of the magic is a special curing process which to me implies a specialized factory process. That may be slow to replicate or scale up. Michelin MXM4 are made in USA and are an old tire design so probably the...

Many OEM tires intentionally have a lower tread depth so they can get better rated efficiency figures. I don't think it's a Tesla peculiar thing but they definitely do it. The MXM4 is notorious for that, and perhaps the same is true for the stock Continentals as well. The Hankook iON EVO all...

Note, not the V12 and not the end to end and not the generative world model

no, not better, will charge slower at 25% than 15%. Do what you normally do or what the car says and don't worry, enjoy your trip. The primary directive is if you can keep your state of charge below 55% as long as possible, including stationary. This is for every day, not road trips---for that...

True, it's a clever step in a direction that doesn't obviously lend itself to making an autonomous vehicle, particularly L3 and above, though. It might prove to be useful but the gap from that to a product is wide. Again true, but the task to be solved by the eventual chatbot (generate novel...

> Moravec's paradox is the observation in artificial intelligence and robotics that, contrary to traditional assumptions, reasoning requires very little computation, but sensorimotor and perception skills require enormous computational resources. The tasks solved by sensorimotor and perception...

Is that with commercial airlines with professional pilots, or includes amateur pilots? if its the first then it's quite distressing given the much higher training of pilots.

And where I am in California, ignoring the freeway speed limit signs, which fluctuate with construction regions (inactive) without cars actually changing speeds, is a better idea. Previously it followed them too literally and caused many 70->55mph slowdowns in heavy traffic.

the second, if you arrive with a low SOC, it will take a little bit longer to charge than if you had NCA. Nothing different for you to do.

247 Wh/mi: 20" Tesla OEM wheels, 235/35/20, Pirelli PZ4 Tesla specific (presumably Elect) UHP summer 227 Wh/mi: 18" T-sportline, 235/45/18, generic Michelin PS4S UHP summer 212 Wh/mi: 18" T-sportline, 245/40/18 nonstandard size, generic Pirelli PZ4. Unclear if All season or summer. Unclear if...

Yes it could---but the density of these valuable labels will be low, relative to the chatbots. "finding video examples of the fleet with desired control" is a major scientific/engineering problem once you go to end-to-end and don't build in a physics/robotics based control system like the...

Some parts are the same but the problem to be solved is significantly different and more difficult in a fundamental way. The LLM's have their bulk of training predicting words forward in text and estimate an approximate world model to do so. The video vision systems do the same, predicting...

it should be the other way around then---should be developing solar & nuclear to have independence.

Why is that hard to believe? It's common that battery cell manufacture is distinct from assembly & pack manufacture, as the expertise involved is distinct and cell manufacturers provide to multiple end manufacturers. In aviation it's common that electronics and engines are supplied separately...

If that were the case then the battery management system would be faulty. I don't know if state of charge refers to current or to energy, but if were energy then 1% of energy should be 1% of energy at any part of the scale. If it were current then there would be somewhat more energy per cent...

I wonder if they can do the opposite of typical Generative-Adversarial networks. Usually the adversarial part is trying to distinguish real from synthetic and the generative part trying to minimize that. But for training drive policy they would want to make it as insensitive as possible to the...

In your analogy the driver would have stopped and literally had no idea what to do until the human passenger informed them---and it's likely not "hey turn right on ash street as it's a shortcut in rush hour" type of driving, but "driver stops and says uh, there is construction and a policeman...

It can never fix the autowipers with current hardware. I and others have written over and over why it's difficult. A physical rain sensor fixes the problem but Elon took it out to save money.

aggressive means means how quickly will it decide to change to a faster lane. I don't think they're going to allow settings on anything that might be safety related. And this is where humans are superior to current systems because they have experience in the unspoken sociology of...

Except it isn't really. It's a high L3 in those cases. It stopped and told a human (back at the mothership) that assistance is needed, and after being given that assistance, it resumed driving. Human assistance for cognitive decision making & routing is still assistance even if it isn't...
