Is this how the US falls behind? Missing technological improvements due to blind disagreements with Chinese/etc, combined with inability to update infrastructure? (Unclear how/why but datacenters being stood up so quickly seems like an exception to US’s bad construction)

It’s a purposeful hamstringing of EV so the GOP’s oil and gas supporters can make 3-5 more years of money.

China's low level of corruption wins again
raddan•1h ago
Unfortunately, a corrupt autocracy with a strategy seems more likely to win the capitalist arms race than a wealthy but feckless democracy. It’s only slightly ironic that said autocracy calls itself communist.
skippyboxedhero•1h ago
Functioning democracies are inherently authoritarian. The simplistic, textbook definition of dictatorship, which in the West is generally used to define the foreign other, has no basis in reality.

This vision holds because it presupposes that the only thing people care about is political freedom, when in reality there can only ever be one political class and political freedom is largely about some other political class trying to take control because the current system doesn't favour them in some way.

Western democracies, at their worst, have a largely permanent political class who is elected every year under the pretext of democratic legitimacy. Eastern dictatorshpis, at their best, have a government that is continuously rotated to ensure competent implementation gaining legitimacy from delivery.

Both are contextual and the position along the autocracy axis largely depends on implementation. Whether people can actually vote is irrelevant (Europe is generally one of the worst examples of this, elections constantly, most election produce governments that polls under 20% within months...it is very strange that people call this democracy).

I mean if you really think about it china already has or is on the verge of:

- energy independence

- ASML level microchip production

- the SOTA of AI

- citizens that accept surveilence and lack of privacy

- strong local manufacturing

- eastern world support

- yuan recognized as a stable world currency

But they do suffer from issues as well:

- Aging population

- Autocracy (or well, one party system)

- Brain drain (better funding and security in the US and Europe, US has managed to alienate a lot of very promising figures so it's closer to just Europe, but capital markets in Europe are still hit and miss)

It's completely understandable why US is freaking out, china's future still looks a lot more promising than the one US find themselves in.

Neither do US and European citizens. We seem to be accepting the same amount of surveillance and lack of privacy still.
Johanx64•1h ago
You're presuming that if they had a choice, they wouldn't accept it.

The reality is that chinese goverment is - overall - delivering results. People will accept things that bring good outcomes.

There's also upsides from the surveilence and the way things are done in China which makes it way more resilient from outside influence and disruptive bad actors.

Now I don't want the same things in my country, but it suits China to some extent.

> citizens that accept surveilence and lack of privacy

It's certainly not to China's extent, but is America really that opposed to surveillance and lack of privacy?

Yes, we tend to raise a huge stink when evidence of such comes to the surface.

But actions speak louder than words, and through our actions we already largely accept surveillance and a lack of privacy.

Everyday consumer apps are some of the worst offenders. Our social media apps listen to us, Amazon Ring doorbells are allegedly accessed by ICE (though Amazon denies it), Flock cameras abound (not to mention the fact they're poorly secured so who knows who else is watching other than the municipalities Flock contracts with), companies own much of our data and sell them to myriad unknown sources on a whim. There are too many examples to list.

No, it's not as severe as China. But we're certainly not trending in the right direction.

himata4113•43m ago
The american government pretends to care, but the moment you look deeper (snowden leaks), it's clear that they don't. But the fact still stands, the population is mostly against surveilance while chinese just keep their head down.
duskdozer•51m ago
How much more surveillance and lack of privacy is there than the US? The US also has

renewiltord•1h ago
For the majority of Americans, “the US falling behind” is not something they care about. The principal thing they care about is not whether the whole is ruined but whether they have an appropriate portion.

An American would prefer that a field make 1 unit of rice if everyone got 1/n units. This is different from cultures where the preference is that you maximize your wellbeing (older America) so that if someone could figure out how to make the field make 10 units of rice, it’s okay if he makes 8 units and everyone else gets 2/n units.

The modern American cultural optimum aims to minimize |x_i - x_j| while growth cultures attempt to maximize x_i. An ironic reversal of roles.

skippyboxedhero•1h ago
America is also, fundamentally, a divided country where people disagree over basic things (such as the distribution of rice) and there is a massive industry dedicated to amplifying that division.

On almost every topic, the discussion will turn to what that other evil part of society is doing to disrupt the good guys. If people are arguing about how to house people or stop crime (both basic issues), you will never move from these topics.

Most visible example is public infrastructure, middle-income countries in SE Asia have better infrastructure than the US (and most of Europe)...this makes no sense within the prevailing political/economic/social context in the West, it should just be totally impossible.

pbronez•1h ago
Maybe. Agree that zero-sum thinking sucks. You gotta grow the pie. But. You also have to share the big pie.

In your example, the current crisis can be represented as:

A field exists and produces 1 unit.

A financial entity buys the field and applies unsustainable methods to increase production 100 units, keep 99.5 of them, distributes 0.5/n. People are pissed that they’re getting half of what they used to despite incredible productivity. The people elect a leader to fix the situation. The leader confronts the financial entity, and returns to the people with 4 units in their pocket and excuses.

America has a genuinely crazy side.

No other country in the world has anything like the Republicans in the US, who are the only major political party in the world to oppose the existence of man made climate change.

There may be political parties in the rest of the world that say that the cost of tackling climate change is too high, but they don’t dispute the factual reality of it.

The Republicans were in this position between about 2008 and 2014 when their leaders were McCain and Romney, but Romney’s lack of insanity inspired a massive backlash within the crazy part of American society that then made Donald Trump their primary winner in 2016 as a repudiation to the not completely insane Republican leadership.

I know HN loves to pretend that the Republicans and the Democrats are just two sides of the same coin, but this can be shown to be objectively false by comparing to political parties abroad. Democrats are a normal European center left to center right party with all the flaws that brings with them.

The Republicans are now a party of insanity.

Europe is third since the 2000s. The pushed the Euro to try to limit it (and from the mouth of someone who was present when they pushed, it was also caused by the black Wednesday of 92, the attacks on currencies increased, and the cost to rebuff them too).

And yes, basically, no one should include europe in the comparison until US oil fields are depleted, and even then at best it would be a race for the second place. You can't compete without gas and oil or a huge manufacturing lead, and europe don't have any, and only have specific subset of manufacturing (basically sensors, electronics, avionics, optics, and handmade clothing) that isn't workforce-intensive, nor resource-intensive.

The Chinese are selling their EVs all over the world.

There are credible American auto enthusiasts that have got these cars and have been using them in the. US.

The superiority of Chinese EVs isn’t propaganda.

The gas pumps maybe are just a ruse but we know they are operating in China since unlike the US auto industry the Chinese one is incredibly competitive so if BYD was lying about their gas pumps the nearly 100 other competitors would have called them out

unethical_ban•46m ago
Put political freedom aside. Does China not have massive high speed train networks, the best EVs on the planet, the most renewable energy growth on the planet and a competitive domestic AI industry, and hugely more engineering graduates per year than the US?

China is what happens when you put scientists and engineers in charge [1][2].

20 years ago China had a single high speed rail link in Shanghai going to the airport. Now they have more than 30,000 miles of high speed rail where they've bootstrapped all the civil engineering, they make their own trains, etc. The system handles over 4 billion trips annually and they built the entire thing for an estimated $900 billion [3], which is now less than the US spends on the military in a single year.

Every $1 you spend on the military is $1 you don't spend on housing, healthcare, education, roads, trains and other infrastructure. Eisenhower warned about this 60+ years ago [4].

because they know there will never be competition

meanwhile the highly educated and extremely savvy prime minister of Canada is now allowing those imports

I wonder if any from Canada can make it down here, they should have same safety standards, is there a huge fee for individuals to import vs corporations?

ahartmetz•1h ago
It happens all the time that a government regulates foreign industries while giving domestic ones relatively free reign. Canada has no car manufacturers. Europe has no Facebooks or Apples. The US doesn't make diesel cars.
andyferris•1h ago
Canada might not own car manufacturers but they do have factories that build cars for GM, Ford, etc, and these are important to their economy. I thought some were sold in the US even?

Chinese companies aren’t exactly building factories in Canada to sell to NAFTA, but I guess Carney figures it’s worthwhile overall?

raddan•57m ago
Many are made in Canada [1]. I remember traveling to Quebec in the early 2000s and being surprised to see more people driving Fords than back home in the US.

I suspect part of BYD’s strategy is to get a foothold in the North American free trade zone. Maybe they won’t be able to export to the US at first. But if I recall correctly, an import US legal principle is that laws/tariffs cannot discriminate against a single company (excluding for national security). So BYD will simply iterate toward a design that satisfies US regulators. I am not familiar with Canadian safety regulations but I would be surprised if they were dramatically different. Unless American car manufacturers can find it in their hearts to sell an affordable car, this is an existential threat.

What are the requirements of vehicles that drive across the border, like if a Canadian family is holidaying in Buffalo?

If they're driving a BYD, do they get stopped at the border?

What if they sold their BYD to a US family? Can it be registered and insured? I'd guess not, therefore it wouldn't get bought by a US resident in the first place.

kotaKat•1h ago
Border-crosser here: Many Canadian-model-only vehicles are driven in the US by tourists and the like - you can bring it in for up to the year temporarily.

https://www.cbp.gov/trade/basic-import-export/importing-car

> Nonresidents may import a vehicle duty-free for personal use up to (1) one year if the vehicle is imported in conjunction with the owner's arrival. Vehicles imported under this provision that do not conform to U.S. safety and emission standards must be exported within one year and may not be sold in the U.S. There is no exemption or extension of the export requirements.

To actually legally permanently import the vehicle, you have to go through the rest of the onerous CBP requirements, validate safety standards, etc, etc - and that's when it becomes a true screwball and it'll never happen. But yes, I guarantee you'll see some BYDs running up and down the Northeast, and very likely spot them around Florida as snowbirds drag them down with them still. I think I'm even more likely in my position to see a BYD with red Ontario diplomat plates, now that I think about it...

My favorite oddball I've seen the most of is the Chevy Orlando MPV. https://en.wikipedia.org/wiki/Chevrolet_Orlando

twoodfin•1h ago
It’s highly impractical to import cars less than 25 years old into the US for anything beyond “show & display” licensing, and that’s only for select models.

Modifying them to meet US safety standards and then getting them approved is arduous and expensive, especially if there’s no comparable US model to emulate / borrow parts.

It seems to be the same small vision that lead to French cars being sold in droves in Latin America.

I think you'd have to be a bit ignorant of very recent history to think that America is some cesspool of lack of innovation in the electric car industry. They invented it, despite there being no competition at the time.
thinkthatover•1h ago
now now, Canada is only allowing 50K of these cars to be imported per year. This is a middle power extending a hand to a superpower in the new multipolar world, nothing more. Also BYD subsidies (and sales) in China have been dropped in the past year.

Is the tech better? Yes. Is protecting domestic auto capability from subsidies in the National Interest? Debatable. This convo always circles around to how we characterize subsidies (EV credits for Elon, direct state sponsorship by China) in a way that's always concealed just enough from the general public to stop people from asking hard questions.

hshdhdhj4444•47m ago
Biden’s banning them was not a good decision IMO.

At the same time, he was encouraging domestics manufacturers to start building their own EVs out, which opened up the possibility of unbanning, with reasonable import duties, once the American companies were competitive.

However, right now we are pushing American companies to go in the opposite direction and dismantle their EV efforts.

With 5 minute charging, suddenly conventional gas stations can be used for EVs just as they are for ICE. Nice thing about 'plugging in' as opposed to 'filling up' is that a charging car can be left completely unattended (while you go to pay, get a coffee, or whatever).

Seems that the technological barriers have been overcome, now we just need to build out the infrastructure - which could be as simple as retooling existing gas stations. No need to electrify every parking space or such like.

Feels like such a waste for marginal gains?

With the range as good as a modern EV the charge time already isn't a particularly that bad. I'd much prefer more chargers (so that you can combine charging with something else you were going to do anyway) than faster ones.

raddan•49m ago
I tend to agree but I think the strategy here is to convert people who stubbornly cling to gas vehicles because EVs somehow defy their expectations. I have been approached many times at highway rest stops by people who are curious and slightly skeptical about the EV value proposition. They see me hanging around the vehicle for a half hour and think “ugh, no thanks” as if that’s all I do when I travel. What they’re not seeing is that I rarely use public chargers at all, because 99% of my charging is done either at home or at the charger in the parking lot at work. It’s really just road trips. Not to mention, if you’re an ICE owner hanging around long enough at a rest stops to notice that I’m hanging around, are you really that much faster on a road trip?!!

Back on topic, I am ok with losing a little efficiency in the fast charging process if it means that more people switch away from a horribly inefficient and polluting technology.

s369610•58m ago
looks like they are aiming for 20,000 this year and already have 4,239 "In the first two months of this year alone, BYD has already completed 4,239 charging stations" https://carnewschina.com/2026/03/05/byd-unveils-blade-batter...

I'll bite. They dumped a lot of power in a small amount of time. Sounds like the perfect job for a mega capacitor to streamline deployments. Other than the successful technology, Mrs. Lincoln, what are your gripes?
nneonneo•1h ago
Based on the figures here, they’re claiming around 400 miles of range added in 300 seconds (60% of the full 677 mile range); contrast this with around 100 seconds for a typical gas pump (8 gal/min) and typical efficiency (30 mpg). It suggests that you’d need around 5MW chargers to truly get to the speed of a gas pump.

On the other hand, 5 minutes is already a huge improvement over 15-30 minutes, and it’s fast enough to remove much of the friction of recharging an EV.

Really wish this kind of tech would come to North America…

Although the thought of getting an electric car has passed through my mind on a few occasions, I'm not 100% familiar with the intricate technical details. (for some reason, the tax incentives where I live are still in favor of continuing with the small petrol car I have. Taxes are primarily a function of weight in the Netherlands, and anything besides a lightweight Dacia Spring would imply significantly higher monthly expenditure for me).

What I'm wondering w.r.t. this article is: wouldn't such fast charging shorten the battery lifespan?

I have experience with ebike batteries. Bosch in particular, with very decent 29E samsung cells, that after 70k km or so, basically halved their capacity. I imagine this effect is severily reduced with a car battery because there are a lot more than 10p, so all the wear is distributed more evenly, and 29E are very old technology.

Toutouxc•41m ago
I believe you meant to write “10S” instead of 10p. I’m not 100% sure, but you were talking about e-bike batteries, which are often 36V, made out of 10 cells (or banks of cells) in series. The nominal voltage of most lithium chemistries is 3.6-3.7V.

EV batteries have many more cells in series, for example my car is 104S, and 800V cars have (obviously) more than 200 cells in series.

And the longevity of car batteries isn’t about wear being distributed “evenly” (a healthy battery can’t really wear “unevenly”, you always load all cells at once). EVs take care of their batteries, they cool them, heat them, balance them periodically, and they don’t actually pull that much power from them. They also keep the cells within pretty conservative voltage limits.

I have a feeling that half the reason they're doing this is that they don't have a good idea how to increase energy efficiency.

Case in point:

2026 BMW i3 - 900km WLTP from a 108kWh battery.

2026 Denza Z9 GT - 800km WLTP from a 122kWh pack.

The former charges at a maximum of 400kW, while the latter at over twice that which saves... about 10 minutes at the charger after 450km of driving(12 vs 22 minutes approx).

Many such examples with Chinese manufacturers putting 700kg battery packs into the vehicles just to be able to say it's this and that kWh.

I don't know about anyone here but after 400km or so I'm done and want to at least stretch my legs.

This is an NMC vs LFP battery comparison.

They have different trade-offs but LFP is gradually taking over from the bottom of the market and heading up market in a classic disruptive manner.

They are heavier but cheaper and safer and better longevity.

>Just taking an existing fast charger with 150- or 350-kW capacity and swapping in the latest and greatest 1,500-kW chargers wouldn’t get anyone faster speeds. The system would need all new “pipes”—grid capacity—to actually move that much current.

The grid doesn't necessarily mean "pipes" or power lines. You don't build a pipeline to every gas station. Mobile charging robots work pretty well in China.
