As one of those people, it isn't always. I'm politically opposite those typically associated with virtual signaling, and I drive an EV because it's way cheaper (total cost of ownership), more fun, and more pleasant than an ICE car.

Environmental concerns didn't factor into my choice at all - far more important to me is the thrill of silent, uninterrupted acceleration and not spending time at gas stations.

We could have carbon-neutral aviation, and not with electric jets. We would need to develop an infrastructure capable of producing jet fuel from other sources, e.g. nuclear power. I don't think we'll ever get energy density from batteries even close to what liquid hydrocarbons offer. We just can't get said hydrocarbons from fossil sources.

Better yet: airships or even ship ships with decent internet connections and coworking spaces. You could work on the way and the extra travel time wouldn't use up your vacation days.
