I drive an SUV and I wish we would Drill of the NC Coast today! I did not buy the Suburban for its great gas mileage but for its capicity to carry my entire family in 1 vehicle. I would like to see you squeeze 3 teenage kids, the wife and a dog into your hybrid. Guess you'd have to either make two trips or use two vehicles and burn more gas than I do hauling everybody in one. Oil is used for more than just fuel in your hybrid. You can find it in just about every product your purchase in its many various forms. Just think how much oil was refined to produce various products that were used to make your hybrid vehicle.
