Even if you believe saving gasoline is a holy cause, subsidizing electric cars simply is not a substitute for politicians finding the courage to jack up gas prices. Think about it this way: You can double the fuel efficiency of any car by putting a second person in it. You can increase its fuel efficiency to infinity by refraining from frivolous trips.
These are the incentives that flow from a higher gas price. Exactly the opposite incentives flow from mandatory investment in higher-mileage vehicles. You paid a lot for a car that costs very little to operate—so why not operate it? Why bother to car pool? Why not drive across town for a jar of mayonnaise?
Tax handouts for electric vehicles are emblematic of an alarmingly childish refusal to take account of circumstances. The U.S. government is deeply in debt. In people and nations with their backs to the wall, one looks for signs of rationality. Running up more debt to subsidize electric runabouts for suburbanites is not such a sign.
