Shocking subsidies for the Chevy Volt

The Mackinac Center for Public Policy has calculated that, so far, the federal and state governments have committted a total of $3 billion to develop the Chevy Volt.  Depending on how many Volts are sold, the subsidy per car could be as high as $250,000.  For reference, the average Volt owner makes about $170,000 per year.  Perhaps they would prefer a new Ferrari 458 Italia instead of a Volt.  They only cost $225,000 each.
