No, please don't tax something because it is wasteful or not, but tax something based on how much resources it uses. In fact, tax the resource usage not the activity.

Even an extremely efficient car uses a ton of energy to move around. New cars often have engines in the multiple hundred kW range, which is insane compared to any other appliance you own.

If fossil fuels were taxed properly, that would discourage using/wasting fossil fuels. But please don't tax based on what you feel is acceptable usage was wasteful usage, cause the atmosphere does not care if the CO2 came from kerosene on a plane bringing tourists to vacation, or if it was used to power the ambulance that brings you to the hospital.

But when we tax all fossil fuel uses equally and heavily, I'm sure the ambulances will still drive around cause they save lives, but weekend trips to the other side of the Atlantic will be a thing of the past.
