That's also the website that had a huge rant about how the new GTR cheated on it's Ring times with no proof. I can see $5.00 a gallon but I haven't seen any other source that projects $10 or anything above that anytime soon.
Here's an article that kind of says the opposite on the topic. I would be fine with paying 5 bucks a gallon if it takes 40% of the trucks/SUV's off the road. Even @ 5 a gallon I can still fill the Miata up for less than $50 and the Elise up for $40.
