That was always my argument. I think that to look at it holistically, you also have to consider people who are adding an EV instead of replacing a normal car with one. Rich people love tax breaks, and they're happy to drive a Tesla with $7k paid for by taxpayers. If you do replace a car, factoring in not just the EV but the effects of that otherwise-serviceable car being scrapped or whatever. Consider also that EVs becoming popular creates more demand in general for cars, so someone is likely to purchase a new EV when they could have just kept using their normal car.
