I was emailed this earlier in the year opinion piece. Its quite provacative, and makes you think about why government policy seems to keep oil use high The American Spectator : The Problem With High-Mileage Cars Which may be part of the reason government policies are set to keep oil use and thus oil taxes high What has been the justification normally is safety. But maybe the government should come clean and tell us the truth, european cars still are safe, and there is no reason we need to push this footprint argument or add weight to a european design for safety.
