http://www.businessinsider.com/uber-and-lyft-limit-personal-car-use-study-2017-8 Ride-hailing giants have said for years that their services will start to kill car ownership by giving urban dwellers a cheaper and more efficient way of getting around. A recent study from the University of Michigan Transportation Research Institute, Texas A&M Transportation Institute, and Columbia University supports that notion. Uber and Lyft left Austin, Texas in May 2016 after servicing the city since 2014. The ridehailing giants called it quits after voters upheld strict regulations on the companies, like issuing fingerprint-based background checks. Uber and Lyft returned in May after lawmakers passed a bill overriding the strict regulations. The departure offered a unique window of opportunity for researchers to investigate how people changed their habits after growing accustomed to ride-hailing services.
