Volvo is committed to making autonomous driving technology a significant part of the automotive landscape by 2020. The automaker says one of the biggest challenges it faces in meeting that goal is the struggle facing lawmakers (from both the European Union and the United States) to develop a cohesive set of rules for autonomous technology. Volvo hopes to assist in that process by extensive testing, including an ambitious plan to launch no fewer than 100 autonomous test vehicles on London’s public roads.
