While buying an EV is a greener choice than buying an ICE, a better option still is to use the vehicle you already have for as long as reasonable. This also overlooks the fact that EVs are prohibitively expensive for the vast majority of the population. It isn't the case that people aren't buying them because of preference. Nearly everyone would buy a car that's cheaper to run and maintain if they could afford it.
Bike > walk == public transit > used EV > new EV > used ICE > new ICE That's pretty much the order of "greenness" in personal transport. New EVs will pay off their added carbon footprint in roughly 1 or 2 years in most locations. The ultimate determining factor of how fast that is the energy mix of your local power generation. The only time it'd probably be better to continue using an ICE is if that ICE is a moped or…
It takes 2-4 years of that mileage alone for a new EV to reach lifetime emissions parity with a new ICE in the EU (which I know is longer than the US due to the vast differences in average emissions per vehicle between the two continents).
For most of the world, the GP is correct. Driving whatever car you have will always be more environmentally friendly than buying a new EV. Reduce and reuse are environmental cornerstones for a reason.
