With the advent of self-driving vehicles and other technological shifts upon us, Gabe Klein asks how we can close the gap between the energized, aggressive world of start-ups and the complex bureaucracies struggling to change beyond a geologic time scale. In Start-Up City, Klein, with David Vega-Barachowitz, demonstrates how to affect big, directional change in cities, and how to do it fast. This book is for anyone who wants to change the way we live in cities without waiting for the glacial pace of change in government.
