While Google has created a concept driverless car, Cadillac has decided that 2017 will be the year that we surrender to our robot overlords. That's when it will release to the general public a car with "limited automated driving capabilities." Details are very slim, but it probably won't be as terrifying as Skynet or as awesome as KITT.
With increased automation, though, comes the question: When there's an accident in a driverless car, who will be responsible? The manufacturer? The driver? What if the driver wasn't driving; should he have been? It's a thought experiment that's coming closer and closer to reality.
