A self-driving shuttle bus in Las Vegas got in an accident on its very first day of operation. The incident was due to "human error" after a truck failed to stop and backed into the bus. It drove up to eight passengers alongside real traffic along a half-mile route, with plans to carry 250,000 riders in a year-long trial. The shuttle was hit by a truck, the City of Las Vegas said in a blog post, after the truck's (human) driver failed to stop in time.
