Lyft co-founder John Zimmer posted an in-depth blog post on Medium about the transportation revolution and the company's future plans.

“I believe we’re on the cusp of nothing short of a transportation revolution  — one that will shape the future of our communities,” he wrote. “And it is within our collective responsibility to ensure this is done in a way that improves quality of life for everyone. The coming revolution will be defined by three key shifts:

1. Autonomous vehicle fleets will quickly become widespread and will account for the majority of Lyft rides within 5 years.
2. By 2025, private car ownership will all-but end in major US cities.
3. As a result, cities’ physical environment will change more than we’ve ever experienced in our lifetimes.

Zimmer said he will partner over the next year with experts in relevant fields to publish a column called “The Road Ahead.” “It will examine the future through the lens of transportation, and discuss the steps we need to take today to unlock an era of unbound social progress,” he said.
