It feels like we are still trying to convince ourselves that EVs are a good idea. Progress is too slow and too painful.
Why wouldn’t they obviously be?

Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer
I heard Kia Niro has the front wheel drive issue and the tires wear on the front very fast. So you should swap front wheels and rear wheels every year to get best wear result. I drive very poorly and fast, but usually mid-range tires last for at least 30k miles on different cars.
This is known as rotating tires, and is a good idea to do periodically for other reasons as well.

I thought about PHEV but in the end went full EV simply because it seemed to me with two whole power trains that's 2x the components to go wrong/need maintenance.
That same insight applies to regular hybrids, and yet Toyota’s hybrids are legendary for their durability. There’s a reason half the cabs where I live are Prius station wagons, and it’s not their efficiency, judging by how they’re driven.
Consumer reports found that HEV's were the most reliable, and PHEV"s the least reliable. That's nonsensical, there's little difference between the two.
Toyota is the biggest seller of HEV's, Stellantis of PHEV. That's the difference. EV's on paper should be the most reliable, but Tesla is the biggest seller of those. If you want reliability, choose by brand rather than engine type.

From your own source: > In countries that get most of their energy from burning dirty coal, the emissions numbers for EVs don’t look nearly as good—but they’re still on par with or better than burning gasoline. Trump's own EPA calls your argument the #1 myth about EVs. https://www.epa.gov/greenvehicles/electric-vehicle-myths
Myth #2 numbers from graphical representation are totally off from the 80% initial C02 difference in the MIT study. IDK where these numebrs come from but I'd tend to trust the MIT more than some propaganda from your beloved president. Same goes for myth#1 IMO numbers are Trump related propaganda and have nothing to do with reality. Furthermore on myth #1 they talk about efficiency of EV vs ICE but totally forget to m…
Ah, we've journeyed quite a ways from "I'm saying it's inefficient because of a combination of many things" to "when you sum up overall efficiencies are identical" in just one comment!
I also trust MIT more than Trump (I'll trust a poodle over him), especially on EVs. The point is even Trump's loony EPA clearly states they're better for the environment, inclusive of coal power. (Which MIT agrees with; I quoted your source!)

which is the whole point of hybrids Part of the point, not the whole point. Regenerative breaking is absolutely a win; but there can also be a significant benefit from allowing the ICE to remain in the RPM "sweet spot" rather than moving around a larger range.
That's the case only with CVT transmission
Are there still a lot of hybrids without CVTs?

the level of regenerative braking directly impacts your accelerator pedal behavior. by reducing regeneration, you will increase tire life by virtue of modifying your acceleration behavior. Its hard for me to explain, but I just suggest trying the medium regenerative setting and you will see it yourself. You will feel it, because the most of the tire wear happens when car decelerates. On less regeneration your car wil…
most of the tire wear happens when car decelerates Is this generally true? I imagine it depends on the car/driver to a certain extent, but still I'd be curious what numbers are out there.
when car decelerates, the kinetic energy has to go somewhere, large part of it goes to battery as regeneration (60%), the rest goes to tire/road friction and wear

> slightly higher tire wear (due to weight) And thus higher tire particle pollution. And it's not slightly, EVs are on average 10-15% heavier than similar ICE vehicles. We've now found that a lot of the various small particle pollution (e.g. in bodies of water) come from tires. So, while still drastically better than ICEs, they still have externalities (pollution, time wasted in traffic, vehicle accidents) and there…
I'm sure you feel the same way about cutting down on cell phones right? How about we just let people keep their cars (preferably EVs), but feel free to go live in a dense cell block and eat bug juice if that is what floats your boat.

That this is considered a valid response to someone suggesting we need more mass transit is a sign that our discourse has fallen off a cliff. You can and should do better.
Re: Electric cars produce less brake dust pollution than combustion-engine cars
#519Good to have more data points and evidence, but this seems extremely well established by now? Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.
>drastically removed brake dust It will be very interesting to see the data for the same car that has many powertrain versions for example the Lexus UX with the UX 200 (ICE), UX 300h (hybrid) and UX 300e (EV) to test which one the best and the worst in term of brake dust residue. My hypotheses is that for brake dust residue the best is hybrid, 2nd will be ICE and the 3rd will be EV. This is due to the fact that the E…
Your hypothesis has already been tested multiple times. It has always failed.

It's hard to share a cell phone. If there are opportunities to make them more environmentally friendly (longevity, production processes, better batteries, etc.) we should absolutely try to do those things.
EVs are better than ICE cars, but shared-use buses/trains/etc. are often even better. We can do more than one thing.
