Critics are calling for a "Passenger Bill of Rights" to establish safety standards for ride-booking services like Uber and Lyft, as the terms of use for these companies place the burden of safety on passengers and admit drivers may pose risks. The proposed Bill of Rights would ensure passengers are entitled to vetted drivers who undergo background checks, have commercial licenses and insurance, and provide rides in safe, functioning vehicles. A poll found 91% of Americans support regulations for ride-hailing drivers, increasing pressure on lawmakers to take action as safety issues with the app-based industry continue to be reported.
