This article was in USAWeekend today. It highlighted what the author considered "green" vehicles; ranging from a $6,200 Vespa scooter to a $106,000 Lexus 600h L with several others in between those prices. And of course, smart was no where to be found.

The print article mentions these cars besides the scooter and Lexus. Mercedes GL320 BlueTec $59,000 (diesel & rated at 23mpg highway) the Honda Civic GX, $25,000 (Runs on natural gas using a $4,000 add-on fuel station to your home gas line) and only 100 miles per charge.
I can't believe the author could overlook the smart car, especially for these choices.
