streets of fast-industrializing
cities were congested with
horses, each pulling a cart or a
coach, one after the other, in
some places three abreast.

at a rate of roughly 35
pounds per day, per horse.

30. The Sharing Economy
• Cars are driven just 4% of the year
• 35% of consumers are expected not to own their own car by 2034
• 60% of US adults say they would ride in an autonomous car
• With a fleet of just 9,000 autonomous cars, Uber could replace every taxi cab
in New York City, and that passengers would wait an average of 36 seconds for
a ride
31. What if all trips in a city were carried out by a fleet
of self-driving cars shared by users?
The Same Mobility can be delivered with 10% of the cars!
