Yeah. We had an autonomous bus here--involved in an accident the very first day that wouldn't have happened with a human driver. The bus just sat there and let a truck back into it.

I also wonder how it fares in a Kobayashi Maru scenario. I chose to cream a construction cone because the guy in the left turn lane went straight. (Admittedly, I think he didn't realize he was in the left turn lane.) I could see the cone wasn't actually protecting anything, could a car do so?
