No doubt this will have an effect on the number of big suv's on the road. At least some good can come from all of this but I think it will be temporary gas prices will either go back down (yes it is possible) or they will start making more if not all cars and trucks hybrid with in a few years including suv's. There are already a few small hybrid suv's and I just saw that Lexus is going to produce a hybrid GS which seems impressive. Hybrids are starting to become more mainstream and more than just economy cars.
