Google says its futuristic self-driving cars needed some old-fashioned human intervention to avoid 11 crashes during testing on California roads

"Bryant Walker Smith, a professor at the University of South Carolina who closely follows self-driving car developments, said the rate of potential collisions was "not terribly high, but certainly not trivial." He said it remains difficult to gauge how Google's cars compare to accident rates among human drivers, since even the best data underreport minor collisions that are never reported to authorities."Read more » about Google says its futuristic self-driving cars needed some old-fashioned human intervention to avoid 11 crashes during testing on California roads
