I would vastly prefer that gas cars be phased out. But I believe that this is a bit different:
Cigarettes don’t offer any benefit beyond making you “feel good.” And you don’t need cigarettes to feel good, and, in fact, literally any other option is better for both you, and everyone around you, save for harder drugs.
Gasoline cars, while poisonous to the world around us, also offer us far greater benefits: supplies and logistics, we can carry goods further, wider, and faster than we ever could without them. And because of that, without them, sure we’d pollute a lot less, but then we’d have a far harder time carrying critical resources to more remote parts of the world where trains and planes can’t reach, and people would starve or lack critical medicine.
As it stands, EVs are not a reliable substitute. They’re getting there, I want them to get there, but I disagree with the notion that cars should be made illegal as things currently stand. I don’t think it’s nearly as cut and dry as cigarettes are. I can only hope to live long enough to see a world where gas powered cars could be outlawed without leaving hundreds of millions of people high and dry.
