FRANKFURT AM MAIN:- The world’s largest carmaker Volkswagen said Thursday it would work with Silicon Valley firm Aurora to create self-driving cars, hoping to deploy fleets of autonomous taxis to city streets by 2021. “With Aurora, VW gains access to an experienced and globally leading development team in software and hardware for driverless vehicles,” the Wolfsburg-based group said in a statement. Founded by former autonomous driving chiefs from Google, Tesla and Uber, Aurora makes technology that has already been tested in SUVs from VW subsidiary Audi with “good results,” German business daily Handelsblatt reported.
