I even thought that the example of automobiles proved the jet engine analogy wrong.
Sure, automobiles aren’t as complex as a jet engine, but they’re still complex, especially the internal combustion variants.
Something like 10 years ago we were laughing at videos of Chinese cars spectacularly failing crash tests, and now China is selling to very heavily regulated markets.
> but they’re still complex, especially the internal combustion variants.
I'm not sure China is known for their ICE designs. Like Korea, I suspect China partially pushed hard for EV specifically because the complexity in a battery + motor system is meaningfully simpler than the ICE equivalent and there's relatively little overlap in many facets outside of some first principles.
Jet engines are like ICE, but with a very reliability threshold. ICE is already complicated, but OEMs will accept a certain deviation on reliability if they need to because occurence might be low and severity is manageable. Not so in jet engine design. A single failure is a big deal.
Chinese automakers do (or did) make ICE and hybrid cars, too.
I suspect it's wouldn't have been good strategy to try to build those cars for the US, CA or EU markets. An ICE engine is relatively straightforward, but hitting emissions and fuel efficiency targets is complex. [1] And the future of ICE cars, especially in those markets, is limited... why build out emissions expertise, when you can get your foot in the door with EVs?
[1] I recently bought a 1981 VW Vanagon which I try to maintain. That's a perfect time period to see how emissions control forces engine design. My engine has fuel injection and EGR, but a few years back has the same engine block with a carburetor; california emissions uses the same engine, but adds electronic ignition and an o2 sensor in the exhaust for closed loop injection control. A couple years later and they added water cooling. Every so often emissions and efficiency standards got harder to meet and you have to do more stuff.
The Jaecoo 7 is the #3 top selling car in the UK right now and it has an ICE powertrain.
Low reliability and safety issues kills car brands. Consumers really don’t like it.
Sure, jet engines are on a very different level of reliability standards, but it seems to me that the concepts are all the same: highly regulated market of low-margin complex heavy machinery where it’s difficult to be a new entrant in the market.
High speed rail technology is not a secret. We in the US just don’t have the will. Auto technology in China was acquired via tech transfers. In order to open mfg in China foreign concerns were forced into partnerships with local companies; moreover there was an effort to obtain foreign trade secrets. Metallurgy for jet fans isn’t one of the technologies the west has tried to partner with China. At this time the UK, the US and Russia hold the lead in that technology -maybe France has some too.

Tech transfers caught China up, but they then innovated on top of that. They are certainly capable of doing so, they just don't see the need when they can simply use someone else's tech.
HSR is just a willingness to say "fuck you" to people who want to hold up progress by refusing to sell land for any price, or who sue to stop a more environmentally-friendly transportation on the grounds of... <checks notes>... environmental impact.
Say what you will, but I don't consider eminent domain to be some kind of mystical technology that only wizards possess.
For automobiles, China didn't compete with the West on its own turf in heavily regulated markets. They embraced EVs from the beginning. Complex auto regulations can't save Europe because EVs are an end-run around all of the complexity of building an economical, low-polluting engine.
Indeed, Europe is talking about relaxing some of its environmental regulations for petrol cars, now that those regulations are more of a barrier to home companies than foreign ones.

Same deal with things like high speed rail.

Mainly copies of Japanese and US designs.
