Cars that can find their way to a destination without the input of a driver have been in the works for long enough that it is no longer a question of if there will be driverless cars, but when. In fact, Volvo has launched a corporate initiative that by 2020 no person should be killed or seriously injured in a new Volvo. The company says it believes that self-driving cars, as well as autonomous driving features, are part of the answer, as they can prevent crashes.
