I have a friend in the car repair business. When I have expressed my desire to buy a hybrid I was told that because I don't do much city driving that a hybrid would not end up saving much on gas. I live in a semi-rural area, average driving speed 40-55 when not on the local turnpike. I can usually get to where I want to go in under 15 miles. What is the general opinion out there for a driver like me?
