The emergence of electric, automated and shared vehicles — and the popularity some of them have found — are seen as signs that the world of transportation could be on the cusp of a more affordable, accessible and sustainable system.

UC Davis professor and transportation expert Daniel Sperling examines these changes in his new book, "Three Revolutions: Steering Automated, Shared, and Electric Vehicles to a Better Future."

Sperling join Insight host Beth Ruyak in studio to discuss how we can guide these transportation revolutions toward an equitable future.
