Lyft co-founder and President John Zimmer took to Medium to post his vision on "The Third Transportation Revolution", which will be fueled by self-driving cars. In the piece, Zimmer claims that autonomous vehicles will account for the majority of Lyft rides within five years. First step was Lyft's partnership with GM, which was cemented when the ridesharing company closed its $1 billion funding round at the start of the year. Later only to launch Express Drive, a car rental program for individuals that need access to cars in order to drive for Lyft. Followed by news that Lyft and GM were aiming to test self-driving electric cars on city streets by 2017. Zimmer believes that private car ownership will end in major US cities by 2025, which will result in a dramatic change in the way cities look than they do today. He firmly believes Lyft's networked fleet will be the winner in the race for driverless-vehicles beating out Elon Musk and his Tesla's business model.
