No snark intended, but doesn't having to constantly pay attention and be ready to take over control negate a lot of the benefit of the self-driving features? It seems like you'd have to apply just as much mental energy to the task as if you were actually driving, so the only real benefit is that you don't have to physically make the motions. In fact in some ways it seems mentally worse, since when you're driving you aren't surprised by sudden turns in front of trams and the like. With self-driving, there's a constant possibility of those kind of surprises, so I would think it would feel a lot like riding in the passenger seat with a new teenage driver.
