Gas and diesel cars don't pay for the damage they cause to the climate, or for the local air pollution. How is that fair?
That is the real problem. We need to properly price in the negative externality. However, that would mean that driving (and even more so flying) becomes almost prohibitively expensive for many. We already saw with the yellow jackets in France that this would lead to unrest.

Governments need to multitask; they need to handle many important matters at once , not focus on one issue at a time while letting others fall to the wayside.
