An EasyMile EZ-10 self-driving shuttle bus travels along a public road during testing as part of the Sohjoa pilot project in Helsinki, Finland, on Friday, Aug. 26, 2016. While driverless trains for many years have served major international airports and some city routes, such as London's Docklands line, automated buses are still being tested.
