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 co…

That's framing the topic completely out of the issue with global impacts of humanity on ecosystemic sustainability, including biodiversity. Less commut and more collective transportation is going to be far more significant in term of global impact, whatever the engine type.

You can do both! Better trains and more EVs replacing gas cars can be done simultaneously!

The real scandal isn’t just battery degradation… it’s that manufacturers have zero incentive to solve it. Your car becoming worthless after a decade suits them down to the ground.

Standard pack sizes scaled by vehicle class: compact ca…

Battery degradation is largely overhyped and there is growing real world data to illustrate that in practice it's not a dealbreaker. Million mile batteries now exist.

Show me a million mile gas/diesel engine.

Also let's not forget that Toyota has a well funded corporate program rewarding employees to spread anti-EV propaganda.

Some states handle this by requiring cars over a certain age to be emission checked before you can renew its registration. Failing cars have to be fixed and rechecked before you can get your tags.

I think they stop checking cars after a certain year. Like, if you are driving a 1980 Buick, they won’t make you scrap it because it’s emission tech is way out of date.

I can only speak about Germany. Here the technical safety and exhaust check are mandatory every two years. The exhaust check is relative to what the manufacturer specified when they first started selling the car. No one is getting their car taken away because technology improved but you can‘t let your car degrade (or modify it) so it becomes more dirty.

I get what you’re saying but I think it misses that battery longevity can be a competitive advantage for the companies with better technology. The Nissan Leaf 15 years ago came with a 5-year/100,000km battery warranty, now Toyota are at 10-year/1,000,000km.

You’d be proving me wrong with this fact if the data showed that they’re moving more units because of this marketing. As it stands the Nissan Leaf is an outlier only in Norway, where it was practically a free car due to subsidies, otherwise their growth is pretty much in line with other EVs.

This seems like something EV buyers would care about. If they don't, it raises the question of why a solution is needed at all.

You mean this, or something else; https://www.motorbiscuit.com/ev-battery-last-3-million-miles...

A theoretical battery that is not actively produced, let alone actually gone the distance…?

On the other side I can tell you at least SaaB has had a million mile ICE car, from 1989. There’s assuredly more than this.

Speaking of smells.... One good thing about driving an EV is that weird oil or hot coolant smells are from someone else's car (and not a problem with your car) (although yes technically many EVs have coolant loops)

As the fleet of EV's age, I'm sure we'll see equivalents... "The high voltage wires were just dragging on the street sparking, presumably with all the safety features disabled" "They were driving with a 10 gallon coolant tank on the roof, presumably because the coolant loop had a big leak and needed continuous topping up".

Where I live there are yearly check ups that you need to do, or you simply cant legally drive your car

“I’ll sell my car before it becomes an issue” - common statement I’ve heard.

It needs to be fixed, because aside from someone being left with the economic bag of disposing of the vehicle, it is actually an environmental issue to build these batteries.

Just not as bad of an issue as running ICE cars for the same period of time.

People tend not to think more than a certain amount of time away for some reason.

Now do the same for internal combustion cars. What a silly argument.

Yes do the same for ICE - very constructive suggestion. Completely unnecessary to call the argument silly though.. There are marked differences in what's needed in an EV vs an ICE, most obvious of which is the giant battery with a very different supply chain.
