On Monday, a self-driving vehicle operated by Uber hit and killed a woman in Tempe, Arizona. While proponents of self-driving technology say autonomous cars will be much safer than those driven by humans, they'll have to prove accidents involving self-driving cars are anomalies rather than signs of technological flaws.
