Good 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.

I am just excited because the more EVs mean fewer idiots in hot rods running without mufflers.

I think these will switch last and will found new opportunities to annoy you once switched.

Earlier quoted context omitted.

What are you doing to your tires that they only last 10k miles? I think that might be a driver error issue, because my EV (a heavier sedan) basically never needed tire replacement barring me running over a screw or something.

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

Are you driving fast(er than with a ICE vehicle) in corners? Since EVs have a very low center of mass, drivers tend to take corners a lot faster than they would in ICE vehicles which is very hard on the tires.

A friend got hit by this as well and since readjusting his driving style (read: not flying through corners for the fun of it) he gets more (but still not equal) miles on his EV's tires before he needs new ones.

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

I don't think banning combustion engines is fighting the right battle, but incentivizing the alternatives (e..g lowering or removing sales tax) is a good idea.

We don't actually want to scrap working cars unless they have reached the end of their life or passed an air quality threshold (UK tests every car over 3 years old, every year, called an MOT). Reduce, reuse, recycle etc.

Popularity has costs, some are waiting in line for 45 minutes to use a fast charger. EV is not for everyone, but those Rivian are nice though. =3

Well given Rivians rank among the worst EVs in the world efficiency-wise, maybe if you care about not spending your life at charging stations, don't buy a Rivian? Or a Tesla for that matter, since Tesla lies about their efficiency numbers and the real-world numbers are middling at best.

It is the low temperature performance that make most EV impractical. A Tesla power pack heater means the charge will be completely depleted if left outdoors for more than a week in winter.

EV are meant for people that live in 4'C to 42'C weather, and have excess capacity on their solar installations. Everyone else is getting subsidized by their neighbors paying for excess electrical capacity. =3

An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.

There are three things at play here: - evs have a reputation for fast acceleration, and many drivers use it. More wear. - evs are heavy due to large batteries trying to match ICE range. More wear. - evs often come with low friction tires to improve range, they wear faster The second two issues should gradually go away as battery (and charging) tech improves.

Low friction tires wear slower, not faster, on account of being ... Low friction. Friction is what wears tires.

Wow. Well, I like that the people that think like this also probably live I places where you are actually driving a coal powered car. Like the clowns in Hawaii that have extra subsidies for EVs… their power comes directly from burning crude oil. I’m an automotive EE, and and the truth about EVs is in a rush to push them out the door, the media and politicians have set the tech back at least a decade by pretending it…

I don't agree with a ban, but burning crude oil (are you sure about that, it's usually refined at least a little?) can have centralised carbon capture and filtration, whereas cars pretty much just pump it straight out. Luckily they made the smoke invisible so it's ok, almost like it's not even there!

I suppose the same should apply to hybrid cars, which outnumber pure EVs significantly [1]. The effect comes from converting the kinetic energy back to the battery charge via generation instead of wasting it via friction, which is the whole point of hybrids. [1]: https://www.consumeraffairs.com/automotive/how-many-electric...

To some extent, but not really. Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop. My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the car at the end.

If all of us renters were forced to convert to electric there’d never be an open charger in any city again for the next five years, because no landlord will voluntarily afford that cost, and no municipal region can pass a ballot measure to afford that cost. California’s impending ban of combustion car sales hinges wholly on a magical DC-charging network that doesn’t exist in U.S. cities yet (i.e. at parking meters),…

Level 1 charging overnight on a standard 120V outlet, while not ideal, is surprisingly adequate. Granted, many people rely on street parking or otherwise don't have a parking spot that is right beside their dwelling, but for rented houses or complexes with private garages/parking areas the size of the lift isn't necessarily "get upgraded service and a bunch of 240V EVSE put in".

That's still an improvement for both global and local emissions.
