>This simplifies vehicles considerably. On the contrary, this much integration makes repairs nearly impossible, meaning you might have to swap the whole unit(for a lot of $$$) when something small inside it inevitably breaks. Check out the articles published by EVclinic that cover such cases. Aftermarket EV repairs are already big business due to how difficult and expensive the OEMs make it.

that's the reason why BYD provides lifelong warrant for their batteries, motors

Which is a scam. As with all car brands, that so called "lifetime warranty" has so many asterisks on the fine print and is only valid if religiously you stick to the manufacturer recommended regular service intervals where they rip you off at every visit.

Get a replacement that is not using it. Power electronics are no longer something exotic.

Do not print a key fob out of PLA. It will not survive summer car temperatures. A better choice is PETG, or ABS and ASA if you have an enclosed printer that can vent outside.

You leave your key in the car? And you don’t run the air conditioner when you are inside?

> run the air conditioner

Look at Mr. Moneybags here with his car that has the AC add on and still functional!

I really don’t understand why this social credit concept has become so widespread. It does sort of exist but not in the big government breathing down your neck kind of way. Here’s an example - you can rent e-bikes and power banks at low cost, they are everywhere. If you don’t return an e-bike or power bank after using it, not only will that company charge you, but you’ll likely get blacklisted from renting more, even…

That sounds awful. What if you have a dispute and they're the ones in the wrong? You can no longer just take your business elsewhere.

understandable that people might have fears like this since this happens a lot in the west in my own experience, but in china you can always argue with them and the customer service is usually way better, or you can drop the nuke by reporting to the authorities.

Protectionism by who? By definition protectionism cannot kill your own country's car industry.

I’m not sure why you think protectionism (by the local government) can’t kill an industry. It happened to American steel as well: the American steel industry was “protected” while foreign steel companies innovated their production processes. The timeline goes like this: 1. Government gets pressured by industry to protect domestic industry from outside competition 2. Domestic industry stagnates as it has no reason to…

It's also said to be one of the ironic long term impacts of the Jones Act (of 1920) in the US. The Jones Act among other things requires all US flagged ships at sea to be manufactured in the US in a hope to protect US manufacturing of ships, but instead in practice just became that most non-military ships just aren't officially flagged as US ships ever. For instance there's generally only one or two US flagged cruise ships in existence in a given year, they get US flagged through manufacturing loopholes (primarily constructed where other cruise ships are, but with enough "finishing touches" in the US to count as US manufactured), are smaller than the average cruise ship, and mostly only exist for Hawaiian island hopping cruises. (This is due to another quirk in the Jones Act that ships traveling directly between two US ports need to be US flagged. Most cruises can easily stop at a non-US port in between US ports, such as various Canadian, Mexican, and many Caribbean island ports, but from Hawaii the next non-US ports can be quite a bit more travel time and traveling to Tahiti and back just to see two different Hawaiian islands can be a bit much.)

Since the closure of Jeffboat in 2018 (among others), there's no non-military ship manufacturers in the US for anything even resembling cruise ship size (and even before that manufacturers like Jeffboat were mostly only making cargo barges) and the US military contractors have basically shrunk to a duopoly. Probably not the 100+ years later expectations of the Jones Act authors.

The point is that you can't tell anymore just by looking underneath and counting the wtfs. I have a friend who's a big Honda fan, amateur racer, a true "petrolhead" but with an intact brain. Runs his own shop. Naturally there was a barrage of jokes when I rolled up in my new Chinese EV, but then we put it up on a lift and there wasn't really much to joke about. The platform looks boring and mature. Things are where y…

From what I've seen of youtube teardowns by mechanics, Chinese cars often have the air of modernity and future tech about them, but under the hood, they like to use technical solutions that were abandoned by European manufacturers a decade ago or more, leading to the cars not being competitive in driving dynamics to what you would get from an euro manufacturer for perhaps slightly more money.

More fun driving dynamics aren't worth the extra twenty thousand dollars you need to buy the equivalent European car, let alone the ridiculous lifetime costs of ownership, such as maintenance.

I mean, seriously. I can buy a shitty Argentine-made base model used 5-year-old VW Amarok with 70K km on it for the same price as a brand new Chinese-made Changan Hunter (whether gas or REEV). The second one is also going to be far, far cheaper to fuel (if you choose the REEV), maintain and repair.

Let's not even talk EVs. Europeans exited the market before it even began. European brands only start to show up at around what, the 70-100K dollar bracket? Sure, the Porsche Taycan is cool and all, but I've never seen one. Meanwhile, BYDs, Deepals, MGs, and a million other random brands are only growing more and more common with each passing day.

That's something you're supposed to do for any and every car. I had to do it on my Japanese cars to keep the warranty.

Also, the last people I want to hear complaining about being ripped off by dealership service intervals are Germans. At least for Chinese cars, you do it for the warranty. For German cars, you have to bring it in for the services at the specified interval (or, in many cases, even shorter intervals!) or else it will blow up in new and exciting ways and basically total the damn thing.

Oh, and the services for German cars start at around 1500 euros. Hope you're rich!

Recent development made it clear the US is no longer a reliable partner and the European aerospace industry is working on reducing the dependence…

I LOL'ed. Saab doesn't have any expertise to build modern aircraft.

An aircraft doesn’t need to be modern - it needs to shot down the other before it gets shot down.

And, as we have seen with cheap drones, all that money spent on making great stealth aircraft has not stopped Iran from blocking access to 20% of the world’s supply of crude.

So, how effective are your fifth generation fighters based on your nuclear carriers again?

While true, imho its more complicated than that * PE, on the whole, has extracted wealth from quality. This is true at both the consumer level and B2B. E.g. its impossible to trust any aftermarket car part manufacturer, and some OEM brands have turned to dogshit too. * "most people just buy trash at WalMart and Amazon" I'd rephrase that to: most people either can't or are unwilling to pay the premium for quality in a…

I'm very willing to pay a premium for quality, I just can't seem to find any reliable signal for quality before buying. Price and brand are both increasingly meaningless signals.

I'm in the same boat. The only signal that I still trust is (for want of a better term) governance longevity, i.e. how long has the company/brand been under its current management structure. This requires some digging, but good salesmen are usually well aware of management changes at their brands. That may not apply to generic clothes shops, but in my experience this still works for tool shops and appliance stores. You'll want to talk to tradespeople though, not sales drones.

Then there's two signals that negatively inform my trust of a brand:

- company size: the larger the company, the lower they start on my trust ladder;

- advertising: when a brand is overly present in the public sphere, that to me signals that they're overcharging for their product.
