1. Poorer people tend to drive older vehicles, so if you solely encourage higher fuel economies by taxing carbon emissions, then the tax is (at least short-term) regressive.
2. You can work around #1 by applying incentives for manufacturers to make more efficient cars should lead any carbon tax
3. If you just reward companies based on fleet-average fuel economy without regard to vehicle size, then it would be rather bad for US car companies (who employ unionized workers) that historically make larger cars than Asian and European companies.
4. So the first thing done was to have a separate standard for passenger vehicles and light-trucks, but this resulted in minivans and SUVs being made in such a way as to get the light-truck rating
5. We then ended up with the size-based calculation we have today, but the formula is (IMO) overly punitive on small vehicles. Given that the formula was forward looking, it was almost certain to be wrong in one direction or the other, but it hasn't been updated.
The emissions just to shuttle rich people from one side of the country to the next (For some, multiple times per day) is insane. You should need to be a billionaire just to afford flying private jets and it should still eat a significant portion of your income if that's what you choose to do.
And for what? Like, we live in the modern era, why does anyone need to travel from NY to Florida to Texas to California in a day?
These guy will never ride a subway or take a train anywhere.
Doesn't mean that anyone engaging in this behavior should get a pass nor that we shouldn't keep advocating for such a tax.
