The math is right but the economics are incomplete. The problem is that the carbon dioxide released should be taxed at a rate proportional to the amount emitted, but it isn't. Not just for cars, but for all carbon sources. Dumping millions of years of stored carbon into the atmosphere on a hundred year time scale is doing some really bad things to the environment, and until the world gets serious about stopping that then polluting with carbon will continue to be free. People can take some responsibility at a personal level though, for instance by choosing to drive a car that releases the least carbon dioxide for the miles covered. It won't make much of a difference, but then, neither does choosing not to piss on somebody else's lawn. How much it should be taxed is a matter of debate. The damage which results has been placed between $50 and $200/ton of carbon dioxide released, and to first order that should be the tax rate. It is around 105 gallons of gas to make a ton of CO2. Using the high end of the damage range, that would work out to a tax of about $2/gallon. Gas where I am is now well north of $5/gallon and going up rapidly. That says the price should be $7/gallon with the CO2 tax included. Even at $5/gallon I'm sure a lot of people are currently regretting driving their trucks and SUVs, and it would favor driving a hybrid. A BEV would be better for this than the hybrid, of course. However, the "who gets stuck replacing the battery" issue is even greater there than it is for a hybrid. Most current BEVs are better thought of as an enormous battery that comes with a car attached rather than the other way around, at least in terms of the price of repairs.
