I was out skating today. Everyone was having a fun time until a diesel truck simply drove down the nearby road. It stunk up and polluted the frozen lake air for a solid few minutes. I hate diesel trucks with a passion and if I live long enough to see it happen, I will celebrate the day they become defunct. Tesla's EV trucks need to deal the same hard kick to diesel trucks that they did to cars.

yeah, its an interesting analogy with smokers and the smell and pollution they spread. they dont seem to notice it themselves, but the non smokers around them and up to 100 meters away all notice them.

I’m not sure that’s really the case here. There’s simply no way you can’t notice bad pollution from vehicles.

Standing near the average car isn’t that bad at all. EVs are way better, but it’s not that bad.

But stand near a car that has some sort of exhaust problem or isn’t burning fuel correctly and it’s bad. Just horrible to breathe.

I’ve found cabin air filters either activated carbon help immensely. I started buying them on someone’s recommendation but I had no idea how much they affected things.

I’ve driven on brand new asphalt and not noticed the smell. I’ve been behind horrible cars and I don’t notice a thing, unless I put my window down and then it suddenly hits me.

All of a sudden lately I’m smelling the terrible cars again. Time to change the filter.

That won't happen until they design a normal truck. The Lightning sold more than the CT and it still ended up getting canceled(ish). It isn't going to be Tesla that does it, it will probably be someone else, and the driving factor is battery capacity. We've got a ways to go yet. It would help to have 400+ kWh batteries and megawatt chargers.

loeg•23m ago
The post-cancellation EREV Lightning is 99% an EV, for the purposes of air pollution. Agree with everything else.
rootusrootus•14m ago
That's why I said (ish). I agree, it's predominantly an EV. I hope they backpedal on the decision a bit and offer both an EREV and a regular EV at the same time. I'm quite happy with my Lightning and will buy another, but I'm not super interested in the EREV as it just adds expense, complexity, and maintenance requirements without offering me much additional functionality for my use case.
xbmcuser•24m ago
Ev trucks have already reached 50%+ sales in China this year so diesel truck will be gone soon but unlikely to be Tesla trucks though.
princevegeta89•1h ago
No surprises.

No matter how we look at it, EVs are much friendlier and safer to the environment. Some people argue the source of electricty can be contested against because that involves fossil fuel burning again, but in today's world we are rapidly moving away from it and towards nuclear/hydel/wind methods for generating power.

I hope ICE cars completely become a thing of the past in the next couple of decades to come.

I just hope "dumb" EV's become a thing soon. I cannot and will not own a smart car any more I want to own a smart TV or smart fridge or smart toaster.
shiftpgdn•58m ago
Just buy one and remove the SIM card.
i80and•50m ago
They often have eSIMs I think, but (depending probably on the car) pulling the modem's fuse can be safe. That's the case for the VW ID.4 at least.
Nextgrid•47m ago
If the modem has no fuse, physically damaging the NIC chip in the module will also work.
wizzwizz4•29m ago
I want the car to be able to contact emergency services, but not to otherwise be able to use the cellular network. Is there a good way to sabotage the eSIM, without otherwise breaking the modem? (This would still allow the car to be tracked via IMEI, but I'm not too worried about that: anyone capable of that is also capable of tracking my actual phone, and anyone buying that data will already know what car I own.)
ebiederm•47m ago
Does the 2026 Nissan Leaf meet your criteria for a dumb car?

All it's connected features appear to come from Android Auto or Apple Car Play. AKA from a connection to your phone.

I like the looks of it because it appears to be a serious EV unlike too many which are just some company getting their toes wet.

46493168•38m ago
Does Nissan still air cool their batteries or have they wised up?
i80and•33m ago
The 2026 redesign has put in a proper liquid cooling loop.

(Battery heating is inexplicably an extra $300 option, and not available on the base trim AFAICS?)

everdrive•38m ago
Does Nissan still not put telematics in the base model in 2026?
everdrive•34m ago
Looking at the specs page the base model includes "Dual 12.3" widescreen displays" Why? What the hell is wrong with modern cars?
rootusrootus•32m ago
Lots (most?) cars are going to LCDs for the instrument panel. The second screen is the infotainment.

> I just hope "dumb" EV's become a thing soon

What business case is there for a "dumb" EV?

By using touchscreens and software for most functionality, you dramatically reduce your supply chain overhead and better enhance margins (instead of managing the supply chain for dozens of extruded buttons, now you manage the supply chain of a single LCD touchscreen).

This was a major optimization that Chinese automotive manufacturers (ICE and EV) found and took advantage of all the way back in 2019 [0] - treat cars as consumer electronics instead of as "cars".

Edit: Any answer that does not take COGS or Magins into account is moot.

The case is that you’ll sell more cars giving people options. Slate is bucking the trend, we’ll see if successful.
derf_•22m ago
The business case is that I will actually buy it. I won't buy "consumer electronics" garbage when I want to buy safe and reliable transportation.
MBCook•19m ago
That hasn’t worked for TVs. Or phones. Or plenty of other things.
jayd16•34m ago
We'll probably see the death of the dumb ICE car first.
rootusrootus•31m ago
The differentiating factor is not EV vs ICE. All cars have or will soon have telematics and such.
tshaddox•20m ago
Are EVs more “smart” than comparably priced ICE vehicles?
seanmcdirmid•13m ago
Not really, they are just newer than the average ICE car. Parent wants an EV from the early 2000s or the 1990s.
princevegeta89•4m ago
Depends. They get a virtually continual supply of standby power that can last for months if left untouched. So from a technology standpoint that enables them to do many things - from being connected to the network, aware of their location on the map, recording camera footage and other remote capabilities. ICE cars do have some of these but the huge battery packs on EVs make these very feasible.
shmoe•12m ago
Have you met https://slate.auto ? :)

Doesn't even have automatic windows.

tombert•11m ago
I don't love smart TVs either, but why not just buy a smart TV and not use the smart features? I have a few "smart TVs", but I haven't even connected them to Wi-Fi, and I instead opt for an Nvidia Shield TV or just a laptop computer plugged in instead.
stevenjgarner•7m ago
Why? Are you worried from a liberty/privacy standpoint? "Smart" EV's are demonstrated to be significantly safer than "dumb" EVs. Waymo’s 2025/2026 data shows an 80–90% reduction in injury-causing crashes compared to human drivers in the same cities. [1, 2, 3, 4]

Have you been in the new Model Y? I was all for the „dumb car” until I tried one of those. Never going back.

You only want „dumb” bc the other car companies fk’d it all up.

SloppyDrive•2m ago
Post crash connectivity (as well as complex video classification) are part of the ncap standards now.

And with the way we are moving to centralized one system architectures, the device that does video processing can be the same soc that does smart infotainment.

Smart connectivity essentially comes "for free" if the manufacturer wants to hit 5 safety stars, so its not going away, and will come to ICE cars as they modernize the vehicle architectures.

MBCook•20m ago
The number of ICE cars I get stuck behind from time to time that just REEK is amazing. I’m in a decently well off area too.

Some putting off soot clouds, white smoke, nothing visible but clearly not doing complete combustion. Sometimes I wonder if half the cylinders are even working.

I’ve heard one car like that is the equivalent of a surprisingly large number of modern ICE cars is in good shape.

I love EVs. I’ve had one for 5 years now, and I’m glad they help. But I think the “are new EVs worse than new ICE” discussions so often miss a fact.

The pollution from ICE isn’t just from very modern well tuned vehicles, things vary wildly. But all EVs use the same power supply (assuming local grid only), so no individual vehicles put off 10x the pollution per kWh.

tonymet•16m ago
tragically, because of efficiency standards, modern engines are known to burn oil .

Otherwise you may be smelling cars who have had the cats stolen.

seanmcdirmid•14m ago
A lot of old cars also since new cars are so expensive.
MBCook•6m ago
I think expense is basically the problem.

Cost to replace the catalytic converter, cost for new exhaust pipes, cost to diagnose ignition timing problems. Whatever.

If the car drives and you don’t have the money I can completely understand why someone wouldn’t get the problem fixed. Even if it means they’re burning a 1/3 of their fuel, that’s still less in the short term than the $1500 it may cost to fix it.

It’s insanely rare I get the sense that the person is running really dirty on purpose.

I don’t know what a realistic fairway to fix it is. They’re probably isn’t one. I don’t think fines would work, it would probably just make things worse. Seems like the kind of thing where a little government group to find the worst 0.1% of cars on the road and just get them back to reasonable levels would be a huge help.

But that’s not how we do things.

MBCook•4m ago
Stolen cars, exhaust leaks before the cat, incomplete combustion so bad the cat can’t cover it up. I assume it’s stuff like that.

It’s not whatever tiny bit of oil gets burned in a healthy engine.

Der_Einzige•3m ago
A lot of Americans take their cat off on purpose for louder noises.

Additionally, a lot of conservatives love to "Roll coal", and literally will shit up the environment on purpose just because they feel schadenfreude from pissing of an environmentalist.

Having spent a significant amount of time in Bangkok - the city center (and many urban hubs) is an amazing walkable place with pedestrian walkways suspended above major roads, lots of frequent public transit (metro, skytrain) that honestly makes my home city of Sydney feel like a developing country.

The only downside is that traffic creates a lot of pollution, and the engine noise (not honking, there's very little of that) is so bad that you need to yell to a person standing next to you to have a conversation.

As a visitor, I can't claim to know how to fix the problems facing locals, however I can't help but feel that urban centers would be 1000x better with mass adoption of EVs (bikes, cars). I have seen a spike in the number of Chinese EVs across the city - however I'm aware that economic pressures prevent mass adoption by the majority of the road-users

presentation•37m ago
To me, Bangkok feels very much like a developing country.

If you go to Chinese cities, the EV adoption has incredible positive effects to the vibe, though. Shanghai’s French concession is so quiet and peaceful now that most cars are EVs.

apatheticonion•25m ago
Try walking around Newtown in Sydney haha. "Charming" multi-million dollar "victorian-style" shanties with public transit that are a 30 minute walk away and break down every few days.

I think tier 1 Chinese cities are in a league of their own though. It's a shame it's so difficult to stay there for a prolonged period of time as a foreigner.

Thailand strikes a good balance of accessibility and development - that said I certainly agree that there are noticeable signs of it being a developing country. Still better than Sydney on balance though.

tbrownaw•26m ago
This study is about air quality in neighborhoods. So it would show the same thing even if EVs just moved pollution from where people use their cars to where power plants get placed, because that's not the question it's addressing.
MBCook•17m ago
People live in neighborhoods.

Even if the pollution is identical, moving it from where everyone lives and works over to more isolated areas where power plants are would still be a big benefit.

We know EVs are cleaner than that. And when the pollution is centralized in one power plant it’s also more economically feasible to apply filtration or particle capture isn’t it?

wilg•7m ago
OK but we already know that EVs don't just move pollution around.
tbrownaw•3m ago
AIUI there are still disagreements about how to calculate that exactly. This study doesn't (and doesn't try to) provide any input towards settling that.
braincat31415•8m ago
Has the study made an effort to exclude any other factors? For example, a reduction in commute during the covid years?
Der_Einzige•5m ago
It also causes roads to be damaged/destroyed FAR faster due to the vehicales on average weighing significantly more.

https://en.wikipedia.org/wiki/Fourth_power_law

It also simply moves the pollution to places like Africa where the extremely dirty lithium mining is externalized away from wealthy westerners.

Environmental externalization.

davidw•4m ago
Tires and brakes still contribute to a lot of particulate matter pollution even from EV's, but they're at least a step up. The best EV's are still eBikes though.
tbrownaw•1m ago
Tires yes, but EVs tend to have regenerative braking which will reduce brake particulates significantly.
