Self-driving cars and electric vehicles tend to dominate global headlines, but some of the most consequential innovations in transportation are happening in far humbler machines. In Shenzhen, China, driverless delivery vans, autonomous sanitation robots, surveillance drones and other experimental vehicles are already operating in public spaces, offering a view of how cities may function in the coming decades.
Forty years ago, Shenzhen, China, was little more than a cluster of villages, home to a few hundred thousand people. Today, it holds roughly 20 million residents and ranks among the world’s fastest-growing megacities. Yet, unlike other urban centers that have ballooned at similar speeds — Mumbai or Lagos, for example — Shenzhen has largely sidestepped the air pollution, overcrowding and failing infrastructure that often accompany rapid expansion. In the second of a five-part series, The World’s Jeremy Siegel explores how the city has been able to avoid the problems typically associated with megacities.
