My opinion:

Trucks used pragmatically for farming or legit hauling stuff is perfectly fine.

Cars used in true rural areas are also fine, because by definition, they haven’t been developed yet, so there’s pretty much no other way to get there.

But in populated areas (not just “cities” but also suburbs and other areas that are not truly rural and extremely spread out), spaces should be designed for walkability, and have good mass transit options. If a neighborhood is being built, put a small grocery store right next to it, so all those people can get groceries without driving. And put a bus stop near it, so they can get to other areas of town they actually need to go.

Cars aren’t going away entirely. They serve a specific purpose. But they’re overused.
