More fitting is taxing new ICE purchases. Lower income folks could still afford cheap, used vehicles, but folks trying to purchase a 50k, 18mpg sports car will find they'll have to pay an additional ~20k based on the car's emissions. You can make it easier to vote for by being tax-neutral and any revenue is used to fund credits towards new EV purchases -5k. The emissions tax and EV discount will be adjusted yearly to maintain revenue neutral. We should be optimizing a maximal ICE tax and maximal EV discount that minimizes emissions across all new cars. People dropping ~35k+ on new ICE cars, while there is an equivalent 35k EV, must pay to account for their externalities in a true market.
