DETROIT: From his laboratory at Pittsburgh's Carnegie Mellon University, automated vehicle pioneer Raj Rajkumar says self-driving cars will evolve step-by-step, with humans staying in charge for a long time to come.
More than 2,500 miles west in Mountain View, California, Chris Urmson, head of Google Inc's self-driving car programme since 2009, has a different view: A fully automated vehicle that requires no input or intervention from humans is a safer choice, and one that could be ready for production by 2020.
