I saw a Prius outside the grocery store last night, idling to keep the occupant warm while another went in to do some shopping. In comparison, my 22mpg minivan was pretty efficient, 'cause at least the minivan's owner had the good sense to turn it off while he was shopping.
As my brother says, "environmentalist" all too often means "person who can not do math." Or logic, apparently.
