But if you actually think it through and do a detailed analysis of the total carbon footprint of an EV vs an ICE car it turns out that building an EV releases about 70% MORE CO2 than building a comparable ICE vehicle, and running an EV on carbon intensive electricity generated exclusively from burning coal or oil isn't much cleaner then running an ICE car.
As a result some studies even suggest switching to EVs won't have much an effect on the world's carbon footprint and hence won't save us from future greenhouse warming.
OTOH, clearly, over time, electricity production will become MUCH more green, which will make the lifetime CO2 footprint strongly favor EV's. Also, we could choose to use fairly efficient BEV's with moderately sized batteries and less weight, instead of making, say, Tesla race-car like performance so much a thing.
Back in the day, when very underpowered cars were common (like in the 70's and even 80's), then more acceleration could be a safety thing, re passing and entering expressways. But now, a perfectly normal baseline sedan with a 4 cylinder engine, like a Camry or a Corolla, accelerates PLENTY fast to safely do those things. (In my experience, a Corolla accelerates like a dog from 0-30 or so, but then accelerates FINE from there, re the speeds used for passing or merging into freeway traffic).
We don't NEED 5000 pound and up cars 90% of the time, for the population in general. We don't NEED 3 and 4 and even 6 second 0-60 times. Last time I checked, my 2017 Camry was about an 8 second 0-60 car, and my 2015 Corolla (which I donated to a family member needing help, which is why I bought the Camry) was about a 9.5 second car.
Also, over time, lithium recycling is clearly improving, and that will help. Between smaller batteries to power smaller more affordable ordinary middle class BEV's and far greener electricity (again, improving a lot over time) plus less mining due to recycling will dramatically change the balance on the overall lifetime CO2 footprint of BEV's.
Which I'm sure you already know, but you have a history on this site of being net negative about BEV's -- not as bad as the AGW deniers, but still negative overall.
And one aspect of how we live will not (and cannot) solve the whole CO2 problem, of course. But each one that chips in to solve over 10% of the problem is a SIGNIFICANT help, especially over the long term.
And as always, the biggest and easiest "fix" would be to greatly reduce the global population (and thus overall resource consumption) over time by having far less children on average, but getting that done is clearly a big problem, especially in democracies.
Given the track record of the perma-doomer blogs, I wouldn't bet a fast crash doomer's money on their predictions.
