Adrienne LaFrance:

As these technology giants zero in on the car industry, global automakers are being forced to dramatically rethink what it means to build a vehicle for the first time in a century. Aspects of this race evoke several pivotal moments in technological history: the construction of railroads, the dawn of electric light, the birth of the automobile, the beginning of aviation. There’s no precedent for what engineers are trying to build now, and no single blueprint for how to build it.
 
 Self-driving cars promise to create a new kind of leisure, offering passengers additional time for reading books, writing email, knitting, practicing an instrument, cracking open a beer, taking a catnap, and any number of other diversions. Peope who are unable to drive themselves could experience a new kind of independence. And self-driving cars could re-contextualize land-use on massive scales. In this imagined mobility utopia, drone trucks would haul packages across the country and no human would have to circle a city block in search of a parking spot.
 
 If self-driving vehicles deliver on their promises, they will save millions of lives over the course of a few decades, destroy and create entire industries, and fundamentally change the human relationship with space and time. All of which is why some of the planet’s most valuable companies are pouring billions of dollars into the effort to build driverless cars.
