I already have the gas car from 8 years ago.
From what I can tell keeping this is way better than buying any new car - of course if I do buy a new one it’ll be electric. But keeping an existing car uses way less co2 than buying a new one.
The only thing that matters, really, is whether you are personally supporting the oil market or the electric market, how much, whether electric generation in your area has a good mix of green sources, and your support for political willingness to embrace policy that identifies and prices-in the side-effects on the environment, such as eliminating subsidies for oil companies. It all boils down to your willingness to put your money where your beliefs are, which for some people is very hard to do, for some people is not very hard to do, and for some people the environment just doesn't factor into their decision making at all. Tragedy of the commons, or will enough people actually care? Those who have the means and the awareness, definitely should.
My car mostly just sits there.
The most environmentally friendly car is a stationary car.
I think we're not talking about cars any more. I think we're talking about a security blanket.
The scrap yards are btw filling up with modern cars quite quickly because people cannot afford to repair new cars, or the cars are uneconomical to repair even after minor collisions. Whereas a lot of old cars (pre-2010) can be fixed on your driveway with easily affordable tools.
