I'm sort of in between. As I read number 1 I was like "absolutely", but then position 2 brings up a good point. Here is Georgia, about half of vehicles are already suicidal utility vehicles or pickuuuuup truuuuuuuuuks! So there is the chance that #1 would benefit, but still, I can see a lot more people buying those vehicles if they got better gas mileage. I am tired of seeing so many of those vehicles, something to encourage more people to get them would not be good. So that leans me toward position #2.
