Lutz does make a valid point though concerning CO2 emmisions. CO2 is a natural occuring compound, that has been here since the days of the dinosaurs. Just because internal combustion engines produce it, doesn't mean they are the only producers. One main contributor to CO2 production is mother nature in the natural decomposition of organic material. Can we stop that, Dubya?

I remember reading at one point a funny (and possibly untrue) statistic on CO2 production... More CO2 is created from cow farts and other animal gaseous emminations than from all the cars in North America. Is CAFE going to crack down on McDonalds? :D

I do agree though, cars do need to be made more efficient in the future.
