I thought this article was poor - fuel efficiency rated top 3 but environmental concerns were 23rd? How are they different - one has real consequences but the other does not. The article could have been quite good on pointing out that people make economic decisions, not pie in the sky decisions. SUV sales plummet when gas prices go up, come back when gas prices go down. If you want to impact fuel efficiency, what is the solution - charge for pollution. If you don't care, don't charge for pollution. It really is quite simple.
Also, this article nicely backs up a point I remember talking about a week or two ago about falling oil consumption in the OECD in relation to oil prices at $50. Oil consumption falls when prices go up - not rocket science that we should expect healthy consumption growth this year with lower prices.
