I was really interested in seeing what Lovins and Cohen had to say about transportation - I find it's an issue with a lot of opinions, even within environmentalism. There's a lot of focus on more efficient vehicles and biofuels, followed up much later with the idea of not needing mobility in the first place.
I'm curious about others' thoughts on something that applies elsewhere as well, but particularly here: Do you think that industry-led change could be sufficient to change transportation? A major focus of the book is on capitalism, but our transport is either publicly subsidized (roads) or publicly run (transit). Vehicle producers have an incentive to make more efficient vehicles - particularly for industry use - but do you think that mobility for the general public can shift as a response to climate change or peak oil without very serious (and likely expensive) government intervention? Just a nagging thought in my head.
