cartechboy writes "Autonomous cars are coming even if tech companies have to produce them. The biggest hurdles are the technology (very expensive and often still surprisingly rudimentary) and how vehicle to vehicle (V2V) communication happens (one car anticipates or sees an accident, it should tell nearby cars). So what are the benefits to self-driving cars? They may save us thousands of lives and not a small amount of cash. A new study from the Eno Center for Transportation (PDF) suggests that if just 10 percent of vehicles on the road were autonomous, the U.S. could see 1,000 fewer highway fatalities annually and save $38 billion in lost productivity (due to congestion and other traffic problems). Right off the bat you can imagine autonomous driving easily topping your average intoxicated drivers' ability behind the wheel. At a 90 percent adoption mark those same numbers in theory would become: 21,700 lives spared, and a whopping $447 billion saved."
