Actually, it about time. It been almost a decade since DARPA Grand Challenge, where self-driving cars raced through a seven-mile course, and almost three years since Nevada became the first state to make autonomous cars legal.

stanley cup being in a car that drives by itself while the driver reads a book is still quite a revolutionary thought for many people. Note to Samuelsson: This sounds like driving in Los Angeles. Volvo trial is just the beginning. The cars will travel on about 30 miles of Gothenberg streets, labeled as typical commuter arteries. They ;ll also have to deal with pedestrians and bicycles and all the regular hazards that cars with human drivers have to deal with on a regular basis.
