Honestly it would not be better if everyone switched to electric cars. Yes, we should prioritize new cars being electric, but building an electric car is worse than using an existing car all the way to the end of its lifecycle. And yes obviously public transport and infrastructure to promote pedestrians/cyclists is also ideal.
There around 1000 life cycle cost analyses that disprove this idea by now. It takes only a few years of driving electric to pay off the carbon debt from manufacturing, assuming average driving behavior.
Of course, this is complicated because we should be dramatically reducing driving. But for most people it does not make sense to keep a gas car as a daily driver.
I'd love to see one of these analyses, this is new information to me.

It does depend somewhat on the specifics but for the vast majority of cases EVs are just better.
They’re still bad mind you, it’s just that ICE vehicles are so much worse.
Edit: This one might be a bit more directly applicable: https://www.carbonbrief.org/factcheck-21-misleading-myths-about-electric-vehicles/
I'm not paying $40 to read the first, but the numbers in the second match my napkin estimations, so I assume it's pretty reasonable in its conclusions.
However, there are other considerations. For instance, if you don't drive much and have a reasonably efficient ICE, continuing to use your existing vehicle may give you the opportunity to wait for EV manufacturing and operation emissions to drop significantly.
I spent some time outlining some formulas to determine the ideal break even points when accounting for multiple factors like vehicle lifespan and rate of efficiency increase but the math got... complicated pretty quickly. And that's before taking into account the non GHG impacts of EV manufacturing.
Suffice to say, it's certainly not as simple as "always drive your ICE into the ground", but it's also not as simple as "everyone should switch ASAP". For many people with relatively efficient ICEs it can very well be worth it to wait maybe 5-10 years for the next generation of batteries to become widespread.
Your study is locked behind a paywall :(
For a fun comparison, I usually run the numbers for our 2004 Audi A2 with biodiesel (HVO100) against the most efficient electric vehicles, based on Swedish grid emissions and then US emissions.
The Audi runs at 4L/100km (real world numbers) x 256g/L (compensated emissions according to Neste) = 1024g/100km
Versus the Hyundai Ioniq 6 (current most efficient EV according to mestmotor in real world testing) with a consumption of 15.5kWh/100km * 41g/kWh (Sweden according to ourworldindata) * 1.15 (charging losses) = 730.8g/100km.
For the US that's 15.5kWh/100km * 369g/kWh *1.15 = 6577.4g/100km.
So compared to a US EV our car runs with a whopping 6th of the real emissions. Assuming the same production impact that your article linked it would take 11tons*10000000grams/(1024-730.8)grams/km = 37517 kilometers
Interesting analysis but I don’t think biodiesel is very comparable for most people. Also, very hard to account for emissions with biofuels, so I’d be curious how accurate your numbers are.
Yeah, this is something many climate advocates say - that it is better to keep the car you have - but I don't think this is backed up by data at all. It's very clear that that EVs are able to save more carbon emissions than in a fairly short period than you would save by not continuing to drive an ICE vehicle, with manufacturing included.
If we were going to have a simple rule, replacing all ICE vehicles today with EVs will be far better for the climate than keeping them.
There are so many factors that play into that, including the energy mix of the country you live in and so on.
The studies I have seen are a bit suspicious as they seem to employ figures that just so happen to support the idea that buying new cars (EVs in this case) is good. This is not to say that these figures are false, but they fit a bit too well into what the likely funders of these studies want to hear.
The real answer is probably: drive less, and only if you absolutely can not do that, maybe consider getting an EV instead of continuing to use your current ICE car.
Okay and why would a single variable be the way to look at this?
Replacing a gas car with an electric car would only be worse than running your current gas car into the ground, if you were buying a brand new EV and were junking your old gas car. A lot of people won’t do that. If you buy a used EV and sell/trade-in the gas car to someone else to use, a new EV isn’t built and someone who can’t afford EV can get your used car.
Obviously pedestrian infrastructure and public transit is preferable if viable, but it isn’t always viable for the average person (at least in the USA/Canada) to switch to those, so having both options is best
Yeah but that means not everyone is switching to EVs, which is the point of the person you're replying to.
We need to phase out oil and shift to better technologies with room for growth and use change that fits better with future realities.
If we keep some cars it means we need oil refineries running, we need oil processed to fuel and delivered to gas stations... if though we could totally cut sections of that out then we could build solar and wind infrastructure and remove gas stations (which are a horrible thing in so.many regards, if your house is next to a gas station it's value will go up when it closes)
Electric infrastructure is different, no toxic and explosive liquids to worry about so it's possible and increasingly common to have a charging pad at a supermarket or even here in the uk there putting them in at woodland trust carparks so you can have a twenty.min walk in the woods and recharge your own.battety while the car charges.
We will likely see an increase in supermarkets and malls using their vast carpark and roof.space for solar panels, likewise remote places like national parks so cars and busses can be charged off-grid with totally green power meaning that no lorries carrying petrol or pilons need to blight the landscape.
We might also see developments in grid management tech to support them too, for example a train station carpark might have a system where all cars are plugged in then charged in batches so as to use only the available excess load currently in their system - if you know your car will be there all day then it doesn't matter when it charges but it will make it cheaper for the rail operator, likewise electric bikes of course though I imagine they'll be taken on the train more often than not where a similar system charges them before the ticket holders destination is met.
Of course this shouldn't be an overnight thing but a transition where ICE vehicles are replaced with electric at.EOL, I (rarely) drive a tiny and very fuel efficient 15 year old car which i brought second hand, hopefully it'll last long enough that my next car can be a second hand electric, even if I have to replace the battery and charge controller to whatever aftermarket system is available. Though I'd love if self-drive allows me to give up car ownership and simply call one to me when required, unfortunately Uber or traditional taxis are too expensive and unable to fill my usecase requirements in most situations.
