the quickest way to help the environment is to switch to electric vehicles.

When you buy an EV, it’s not a replacement. Your old car is shipped to Africa where it runs for several more decades. So you’re just adding another harmful car to the planet.

The only wise move AFAICT is to convert your car to an EV & then perhaps use the engine to build a backup power generator for your home. But this won’t happen because suburban car drivers are addicted to convenience and nice new things. They are happy to have this false ecology excuse to buy a new car.
