The problem with subsidies for purchasing electric cars right now is that it only helps the rich. Middle to low-class people who need vehicles cannot afford electric cars because the lack of infrastructure makes up front costs very substantial. I guess you could argue the need to start somewhere, and very likely to see full blown change you'd have to start with the rich. I'd still feel crabby about my tax dollars going to pay someone who has more than enough money to purchase the electric car without the subsidy. Most people with an i3 or tesla have a gas fueled car as well.
