Mobility-focused venture capitalist Olaf Sakkers has been a friend of the show for a long time, which is the only reason Kirsten, Alex and Ed agreed to read something called "The Mobility Disruption Framework." We're glad we did though, because Sakkers is far from the kind of empty-headed, buzzword-spouting consultant who has given "mobility disruption" a bad name. Olaf joins this week's episode to explain his funny, insightful book about the trends and technologies transforming the ways we get around, which you can read for yourself at www.yellow.cab.
