On November 8, Las Vegas, a city in the United States, launched a very interesting pilot project. As part of the project, electric buses offer free rides in a part of the city. The really neat thing is that the buses are self-driving! Unfortunately, within two hours of the start of the project, one of the driverless buses got into an accident with a truck. It turns out, though, that it was the truck with a driver that was at fault! The truck drove into the path of the bus.
