I have to admit, I did not think we were quite there yet, but I guess we are. You can now take a ride on a self driving bus in Las Vegas. Its route runs a half mile circle. There is an attendant on board that can take control of the bus with a joystick. Seems the biggest problem they have run into so far is kids jacking with the car acting like they are going to jump out in front of it causing it to self-stop quickly. Damn kids.

“It’s an issue; it’s a common thing that kids want to prank it, and skateboarders dart in front,” said Moreno. “We’re working with the city of Las Vegas to address it. We’re in brand-new territory; there’s no current ordinance right now for that type of thing.” In other words, it’s possible that “don’t tease the robot shuttle” could become a new law.
