You won't be attacking rampaging Google robot cars with pulse rifles in a government-mandated future carless dystopia. Have the driverless light rail systems of the world gained sentience and conspired to overthrow their human masters?

To see this Google car prototype and fear a driverless future is to miss what Google and its co-founders are saying quite openly: this is intended as a large-scale solution for large-scale spaces, not suburban individuals. It's mass transit on an individual scale, for people who hate commuting. This has nothing to do with people who like to drive.
