By Alexei Oreskovic MOUNTAIN VIEW, California (Reuters) – Google Incs self-driving car technology likely will not be available for several more years. A fleet of Googles robot cars ferried more than two dozen reporters around Mountain View, California, on Tuesday, in 30-minute ride-alongs that showcased their ability to automatically and safely navigate around city streets packed with cyclists, pedestrians and traffic signs. The demonstrations, along with a morning of press briefings by Google managers developing the technology, marked the companys most concerted effort to date to provide an up-close look at the cars conceived five years ago in its secretive Google X division. The public needs to understand that a self-driving car is \not something that you need to fear but something you need to embrace,\ said Ron Medford, a former National Highway Traffic and Safety Administration official who is now director of safety for Googles self-driving car project.
