This collision, like 90 percent of traffic incidents on our roads, was the result of human error. The truck driver got a ticket from the Las Vegas police. We could see his mirrors the whole time and he should have seen us. But I don’t want to be too harsh on the guy – driving a big truck in Las Vegas is a tough job, and he’s only human. His error could have happened to anyone.

On the other side, the shuttle did exactly what it was programmed to do, and that’s a critical point. The self-driving program didn’t account for the vehicle in front unexpectedly backing up. We had about 20 feet of empty street behind us (I looked) and most human drivers would have thrown the car into reverse and used some of that space to get away from the truck. Or at least leaned on the horn and made our presence harder to miss. The shuttle didn’t have those responses in its program.
