Here's an new counter-argument: self driving cars are conscious. They're aware of their surroundings, in considerable detail and with useful understanding. They're not passive, waiting for questions; they have an ongoing stream of intellectual activity, so they have an "inner life". They learn from experience. They have goals, some of which are more important than others. They try to predict the future ("will that car ahead try to make a left turn?"). They interact with others (lane merging requires this.) It's not human-level consciousness, but it's consciousness.
So there.
