Yet, researchers, as reported by the "Atlantic" in 2015 (see below), said this:
"Researchers estimate that driverless cars could, by midcentury, reduce traffic fatalities by up to 90 percent. Which means that, using the number of fatalities in 2013 as a baseline, self-driving cars could save 29,447 lives a year. In the United States alone, that's nearly 300,000 fatalities prevented over the course of a decade, and 1.5 million lives saved in a half-century."Of course, that assumes that the technology is sound. In fact, in late 2015, "USAToday" ran a story that stated: "self-driving test cars are involved in crashes at five times the rate of conventional cars."
Google and other companies such as Ford are pushing to put unmanned vehicles on the roads right-now, I personally think the states should slow down a bit and let the technology prove itself with lower accident rates. As reported by the U.K. Daily Mail, a "leaked" internal report from Uber said that a self-driving Uber vehicles can't drive a mile without human intervention. Doesn't sound like the technology is quite there, yet!
