Earlier quoted context omitted.

People don’t want cars they can tinker with, they want cars they can get repaired instead of replaced when something breaks….

People actually want a convenient and cheap service for getting around. All other considerations can be derived from this. If it was cheaper to replace the car than get it serviced, they would replace it. Currently this is almost never the case of course, but if it happens in future, watch people switch behaviour instantly.

well, people want to have enough money to do what they need to do, of course, so they will choose things that they can in order to minimize cost and time spent, and increase convenience. That doesn’t mean they don’t want to own things that can be repaired. Owning repairable things is also valuable. I don’t think anyone actually wants to “own nothing and be happy”. But they might be able to be coerced into it, sure.

Having a mechanical key hidden in the electronic key fob is nothing new, it’s common on many cars.

I guess my intent was not to point out that it has a mechanical key, rather that the description of the key on the webpage was wrong (it is not hinged). The mechanical key fallback pattern is standard across the industry for sure.

It's entirely possible that the BYD key they scanned and the BYD key you possess are of different designs.

All you need to know is that BYD cars are good enough that the US had to effectively ban them.

I don’t think BYD would be a hit in the US as they are in Europe. It’s an entirely different market. They may be relatively successful just not to the point of taking an important market share, they would probably be like Mazda. Many of the subsides for Chinese EV ended this year too, and they are now realizing price alone is not a differentiator. So even if BYD eventually makes it to the US, they will be priced clos…

They're selling well just 5 miles from El Paso with reportedly much interest from US customers.

> Fourteen pins in two parallel rows carry every signal this panel produces to the rest of the vehicle. Automotive connectors are among the most common failure points in modern cars: corrosion, fretting, and thermal cycling work on these joints over years of use. One connector failure on a module this integrated takes out mirrors, windows, locks, and child safety all at once.

Pack that shit full of silicone dielectric grease, check it every year or two, and it should be good for decades.

This was stated about the key: "Folded into the base is a mechanical backup key, a flat metal blade in a hinged housing." I own a BYD: this is not true. The key is not hinged; rather, the entire mechanical key pulls out when a small clip is unlatched near the top of the assembly (you can see it in the CT). I assume the circular hinge-looking mechanism in the CT is just a by product of the plastic/metal weld process.…

And yet my Hyundai key fob, despite being the largest fob I've ever seen doesn't do this :/

> The last company to vertically integrate a car from raw material to finished product at this scale was Ford. Today BYD’s system runs all the way from the lithium mine to the port. Both BYD and Tesla claim to produce around 75% of their components. Ford is at around 25%. Tesla is indeed smaller in scale (cars/year): BYD 4.6M Ford 4.4M Tesla 1.6M

So BYD for cars and Samsung for phones and consumer electronics more generally (from fab upwards). In fact, I believe Samsung is the only company on the planet that can design & build a state of the art smartphone from scratch - silicon/fabrication, SoC, battery, baseband, camera sensor, memory, and display. What other high tech vertically integrated producers exist in this group?

IBM

I want to buy a Chinese car and I am annoyed that my protectionist government won’t let me. Lowering transportation cost would be the most impactful thing to my budget.

All that serves to do is ensure the American car industry falls far behind by being coddled into a lack of competition.

Toyota showed the world the Toyota Production System. What Tesla, Kia/Hyundai, and Chinese EVs have shown American automakers is how much vertical integration can be an asset, especially with the lower part counts of electric vehicles.

The model where every part is contracted out to parts manufacturers is proving to be antiquated.

This looks like a stealth advertisement for their CT scanning business. There is nothing educational of value for the general public here. The only reason you would do this is for competitive analysis and I assure you the other car companies have already analyzed these parts.

It's called content marketing, and there's nothing stealthy about it in particular.
