Waymo, a self-driving vehicle company, has announced plans to launch its fleet in Portland, Oregon. The company plans to manually operate the cars to familiarize them with Portland's streetscapes and help reduce traffic-related serious injuries and deaths. However, some city leaders have raised concerns about potential safety risks and economic impacts associated with the autonomous vehicles. The autonomous vehicles are already found in major cities such as Los Angeles, Phoenix, and Houston. The expansion of these vehicles could help Portland officials achieve their goal of reducing traffic deaths and serious traffic injuries.
