But don’t they cause higher pm2.5 and pm10 pollution from braking due to the fact that EVs are heavier than vehicles powered by internal combustion ?

#142No 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.

Re: Adoption of EVs tied to real-world reductions in air pollution: study
#143Having 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…
There will be no new fast subway in San Francisco and there will be no maglev in NYC. There will be no autonomous buses in Sydney and London will be entirely devoid of skyways.
This is the nature of growth. One grows then dies as one fossilizes. The next one grows past but no one will ever reinvent themselves.
This is why death is crucial to improvement.

My previous car had its infotainment system reboot several times while I was on the expressway. The idea of my instrument panel, or other more critical systems, crashing and rebooting while driving terrifies me.
The infotainment is not connected to the ECU and other car control electronics. At least not on my Tesla nor my F150 Lightning. You can reboot them to your hearts content while driving down the road.

#145Really step back and imagine a world where the modern EV [1] was first to market and a gasoline combustion engine was second.
Who would actually decide to switch from a modern EV to gasoline on purpose of their own choice?
The downsides of gasoline cars are actually pretty crazy: complicated engines and transmissions with heavy maintenance schedules, emissions, more NVH, worse interior space and packaging, need to wait for HVAC rather than it being ready ahead of time, need to go to a special gas station to add fuel, worse/slower performance.
You would have this laundry list of downsides and your only potential plus sides are faster fueling on road trips over 4 hours long, lower curb weight, and lower cost.
And those three minor down sides are very likely to be resolved sometime within the next 10-20 years.

Less commut and more collective transportation is going to be far more significant in term of global impact, whatever the engine type.

It gets studied. EVs are often heavier, which is worse for tire wear, but use regenerative braking, which is better for brake dust. Overall, EVs are likely a net win on the combination of these two things, and a big win on exhaust emissions, but it would be nice if we could shift to lighter and smaller vehicles and increase the mix of non-cars such as e-bikes and mass transit.

> but use regenerative braking, which is better for brake dust Which unfortunately also increases tire wear from regen braking during periods when an ICE vehicle would be coasting without braking. EVs are much (much much) better for CO2, much better for brake dust, and much worse for tire dust.

The surprising part to me is that there are now enough EVs to make a measurable difference, since I kept thinking they are still relatively rare. The linked study has this piece of data: From 2019 to 2023, ZEVs increased from 2.0% (559943 of 28237734) to 5.1% (1460818 of 28498496). So 1 out of 20 cars in California is an EV.

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…
I'd say that putting off sooth clouds is a way to sequester carbon (which obviously failed to burn). Such over-enriched fuel mixes must generate much more CO though, and I wonder if those who "tune" their cars like so take care about the catalytic converter :(
All in all, a well tuned ICE is better for everyone than a poorly tuned one, if you had to pick between the two.
