With this future in mind, GM invested $500 million in Lyft as part of a shared mission to deliver autonomous vehicles worldwide. Not only will self-piloting vehicles change how we commute, they could affect how we craft our cities and even buy cars. If Lyft co-founder Logan Green has his way, car ownership and operation will be a luxury, not a necessity. We may even purchase cars like we purchase smartphones—discounted and attached to a network. And that could forever transform the face of our cities, suburbs, and cars themselves.
