Cars In Crisis? A View From The Detroit Auto Show
As the auto industry struggles, the Detroit Auto Show has been dramatically scaled back. Auto writer Paul Eisenstein, who's been covering the annual event, talks to guest host Dave Davies about what this year's gathering says about the current state of the industry.
Eisenstein writes for The Detroit Bureau, an independent auto-news service. He has reported on the automotive industry for more than 30 years, and was the publisher and director of the auto-news Web site The Car Connection.

Daniel Sperling: A Billion Cars And Counting
Transportation expert Daniel Sperling estimates that the world's car population — which currently stands at one billion vehicles — is likely to double in the next 20 years.
Sperling is the co-author (with Deborah Gordon) of
Two Billion Cars: Driving Toward Sustainability, a book that considers the environmental impact of so many automobiles and suggests ways that politicians, car companies and the general public can curb car-ownership and reduce climate change.
Sperling is a professor of civil engineering and environmental science and policy at the University of California, Davis and the founding director of University of California, Davis' Institute of Transportation Studies.
