Smart cars are alright but do not meet the transportation needs of the majority. Buying one would be a waste of money for many. Take my Jeep Cherokee for example. It gets 20 MPG combined average with four people aboard. To separately move the same people the same distance for the same fuel each would need to achieve 80 MPG individually. With my Diesel Rabbit its more like 200 miles per gallon per individual. For us to use two smart cars or electrics we would use up twice as many tires and we would spend twice as much on insurance and other taxes. Never mind the initial purchase price difference.
What impresses me most is how fast these changes are occurring.
This is why I'm not worried about alternative energy. When the need presents itself (read: when gas gets expensive and stays expensive), creativity will kick in.Mike
