Tax credits needed for now
We need to dramatically cut down on CO2 emissions so EV's are the way to go until we figure out how to do without cars altogether (not likely in the near future). Nissan is already cutting the cost of the Leaf to sell it in the U.S. (much more expensive in the U.K.), but most people still can't afford the price tag. We are planning to buy one, ONLY because the combination of federal tax credit, no state sales tax on EV's, and free charger/installation through Ecotality makes it somewhere within the realm of affordable. Not really, but we want to 'walk our talk'. If even one of those subsidies were missing, we would not be able to afford it. Once they have sold a certain number of cars, the subsidies go away. By then the cost per vehicle should come down.
