I mean after about a decade I finally gave in and bought a used TV (instead of using a PC monitor). I already don't fly to useless tech conferences, and work remotely (so no mindless daily commute).
And eventually when the e-charger network will become widespread enough around here, I guess, I'll buy a used EV instead of the current car, because cities can't ban these smoke machines fast enough.
And when the choice is presented I already buy local stuff.
But.. this is a luxury for me/us, because of the enormous income inequality bonus of IT/tech.
Those who already live on the edge won't pick the local things, they will pick the cheapest one. And the way to make the GHG-friendly stuff cheap is to tax the shit out of the GHG-positive things.
And that unfortunately seems like a pretty hard challenge, thanks to our wonderful society favoring chauvinists rhetoric, trade wars, nationalist triades, and other bullshit.
So, yes, in terms of the big picture EVs don't matter much, but without even presenting an alternative, it'll be quite impossible to persuade the other half of society.
