These older battery cars are now littering the islands.  Once they reach an age of five or six years their batteries no longer hold the same charge and need replacing.  By then they are paint faded, old cars like any other car, and people don't want to pay the $8,000 dollars for new batteries.  Then they sit and become hazardous waste buckets. You see them everywhere already.
And, here in Hawaii how is that electricity used to charge them come from?  Bunk oil burning at the power plants.  Hardly "Green".
