Submission + - PHEVs look great on paper, but real world data says otherwise (theguardian.com)

shilly writes: PHEV manufacturers and advocates claim it’s easy to drive mainly using the cars’ batteries, keeping gas in reserve for long trips. That may be true in theory, but in practice, data from 800,000 PHEVs in Europe shows that between 2021 and 2023, these vehicles were driven using their batteries for just 27% of the time, instead of the 84% figure used in official estimates. It turns out that merely providing the option for driving on batteries in a car isn’t enough to persuade people to plug in, and that EV proponents, who have long argued that PHEVs are not a viable solution, have a point after all.

Comment Re:Part of this decline is all MBA-driven (Score 1) 187

Makes me wonder if AI can take something from the top layer, go through the entire stack, and compile something in machine code directly, all statically linked, with bounds checking. Basically a next-gen transpiler/compiler.

Could a commercial AI do that? Yes. Will it? No. Follow the money. Firstly RAM is free, because the customer pays for their hardware, not the app creator. Secondly the driver behind AI coding is not to make things better, it is make thing cheaper by making them faster, quality is not a requirement.

There are two exceptions to this. Firstly the AI providers internal programs. Training an AI is resource heavy so you can be sure they have optimised that as much as possible, to save their own money. Secondly open source, where the driver is functionality, not profit. First we need to see the AI hype bubble burst and AI to settle down in to being an evolving tool. Then maybe what you are thinking could happen.

Comment Distrubing metric (Score 2) 15

I find using gigawatts a disturbing metric for AI and a reflection of one the bigger problems with AI. One of the biggest differences between the Intel 4004 from 1971 and a processor today power needed to perform a function. Maybe a more relatable example is how much more processing power a smartphone has to day compared those from 2010 while having similar capacity batteries.

With home appliances, lighting and heating improving in recent decades the world had made tangible progress in it energy demands which when coupled with renewable energy sources gave some hope for the future. And now we have new articles about AI companies bring online coal generation for their fucking data centers. Topping this off we have OpenAI and Broadcom boasting about plans to deploy 10 gigawatts of custom AI chips. I far rather hear them boast about custom AI chips that used less power per user AI query.

The metric of how many watts an end user AI operation needs should be the focus, and by all account the Chinese lead USA companies on that metric. How about OpenAI and Broadcom stop boasting about how much worse they are fucking going to make energy demands and instead boast about new technology about how they are going to help reduce the harm they are doing?

Comment How would you know? (Score 1) 83

I consider myself quite well traveled, having even traveled to several states in the USA, but find myself wondering how I would even know if the Internet had a Philly accent? I suspect my knowledge of Philadelphia is about typical of people on the Internet. Here is what I know about Philadelphia:

- It is the name of a place in the USA.
- It is probably a city name.
- It appears in the title of some movies or TV shows, but I can't name any of them.

So today I have also learnt it apparently has a distinctive accent, but I still have no idea what that would sound like. I would hope residents of the USA would know more than the average person on the Internet. Regardless I suspect the article is bullshit but can't know that for sure because I have no idea how to tell given my limited knowledge of Philadelphia.

My comment about how long you keep a car was more about new buyers who turn over their cars frequently. In this case parts are not an issue as it is under warranty and therefor the importer's problem. Actually here the supply of parts would actually extend well pass the seller's warranty due to our strong consumer protection laws, but that would not be true in the USA.

Again the BEV part is not relevant, it is Chinese part that is relevant. I would share your concerns about some Chinese brands, but Great Wall Motor for example, has been selling well here for over a decade is consider an ok brand. BYD likewise are a reputable brand that have been around a while, they are the makers of the world's fastest production car, the Yangwang U9 Xtreme. From what I can see the junk Chinese brands don't export yet, the brands that can pass the international vehicle standards are the brands that have been around a while and have learn how to do proper engineering and after sales support.

Depends on how long you plan to keep it. However when old enough it could be valid point, BYD simply don't have the history outside of China to say how that will play out. However that has little to do with BEV vs ICEV and more to do with China being a new player in the international market. I would say that BYD have been around for a long time and have been selling BEVs for about the same amount of time as Tesla have. I had a BYD from 2012 to 2014 when I was living China and found BYD easy to deal with back then.

Comment Re:They are failing because Toyota sucks at tech (Score 1) 137

A pretty fair summary of things. Not so sure about "Toyota likes making money, so they'll figure it out." given they are pretty much the most indebted company on the planet and are moving a glacial pace to develop credible BEVs while still loudly shouting how BEVs will fail because hydrogen is the new miracle fuel to will take over real soon now. A shame as they did know how to make solid quality vehicles.

I doubt it, here in New Zealand you can already by a BYD BEV, with no subsidies, for the same price as the mid model Corolla and save money on running costs from day one. Top be fair maybe Corollas will still be selling well in the USA in 10 years because ..., well because it is the USA. But in the rest of the world the days of the Corolla being a top seller are number already.

Comment Last month in Japan (Score 1) 137

I was in Japan for 10 days this September and made a mental note of all the BEVs I saw in Tokyo and Sendai:
4 x Tesla Model 3s being driven on the road.
1 x Porsche Taycan parked at a home.
1 x BYD Atto 3 being driven on the road.
1 x Nissan Leaf or Ariya parked on the side of the road.
1 x Tesla dealership in Sendai.
1 x Nissan display across the road from Tachiyo's hotel in Ginza with a formula-e, an Ariya and a Hyper Force.

No FCEV of any brand or any Toyota or Honda BEVs were noticed. By contrast once back in New Zealand I saw more than 7 BEVs on the 5 minute bus ride between the Auckland International and domestic terminals. I do like Japan but they feel really behind the times when comes to BEVs.

Comment Moving in the wrong direction (Score 3, Interesting) 43

I like the idea of AI but I am uncomfortable with the reality of how it is unfolding.

Learn to code was a reflection of the rise of power of the individual in the 1990s. The mainstreaming of the Internet allow individuals to freely communicate and share ideas. The rise of coding tools like gcc allowed individuals to create new things. The rise of open source allow those individuals to create communities that further improved what individuals could do. All of these things allowed individuals the freedom to create and achieve things they wanted under their own control.

Enter AI. At first you had things like ML where individuals could train with resources at home and potentially create a useful solution to a niche problem. But it then pivoted to AIs being all about LLM using massive resources to create the latest models. The power to do this was only in the hands of corporations with deep pockets. The role of individuals this new vision of AI was to be the consumer. The 'Learn To AI' is just a way to say learning to pick which corporation you will be paying your subscription too.

So I am learning to use AI to ensure I can best understand its current abilities and limitations, but I am not excited to do so. AI had so much promise back when it was science fiction, but the reality today is depressing. I would be interest in replies that see a different path for AI that gives some control back to the individual.
