Also, it's quite possible that, the people with EVs will pay more in taxes,
than someone with a gas-guzzling SUV, since the SUV driver will want to cut down on his driving, while the owner of an EV might be tempted to use that energy-efficient vehicle a lot more, which will add to his/her number of miles driven. At that point, the EVs will have lost any advantage they might have had when it comes to saving money.
